thats quite a toughie. how about some lacto-fermented veggies, dry sausages (im thinking specifically about this armenian sausage that my family makes called "soujoukh" (sp?) but im sure many cultures have similar things, similar to jerkey and ive actually never seen it WITH nitrites at our local armenian grocery), canned herring, lara bars and since it sounds like you will be pretty active, what about some tubers and root veggies? turnips, sweet potatoes, celery root, jicima (sp?), kohlrabi, parsnips, etc. nut butters, trail mix with dark chocolate, berries, nuts. ill edit as i think of more, but you can probably afford to eat more than your normal amount of carbs while youre out there, too.

do you do dairy? what about kefir? or, again we (armenians) call it "tahn" and its a fermented yogurt mixed with water and a bit of salt sometimes cucumber drink that is really quite filling and refreshing.

This could be a good opportunity to get used to Pemmican. US Wellness caries some, but I think theirs is perishable.

Also, I second the sausage idea. A couple interesting things to take would be carob or chocolate, to make drinks with.

Some things to consider would be. Is there a cold stream/river near by? If so you can use it for some amount of refrigeration. Seal things in a zip lock bag or two and put them in a cooler in the river. If there are any culverts near you with descant water flow they stay pretty cold. Build a little platform in them out of branches and keep your cooler on it. It's not as good as real refrigeration but works better then nothing. Both these options could be a problem if the area is susceptible to flash floods or has a high bear population.

Wild foods could be good. But the problems I see with them are. Having kids around some of them may try to emulate you or think it's safer then it is and just start eating stuff. Also if you are not very knowledgeable about plants you could make a mistake easily. Being far from civilization and uninsured? not a good time to get sick. This is not to say you can't use them you would just have to stick to the easy to identify ones and maybe not include the kids. Plus allot of wild plants tend to require a fare amount of energy and time to gather and process. Thats why we live in communities and eat lots of meat.

some other foods to consider

tuber or plantain chips=fry some starchy stuff in coconut oil I like plantains use a ratio of 3 green to 1 ripe make allot put it in zip lock bags. Also good is taro, and yucca.

smoked salmon=look at places like canned food warehouse for cheep but still wild caught.

rillettes=needs to be kept somewhat cool. Easy to make lots of energy!

canned butter=look for Vietnamese grocers near you they seem to carry this or order online

hard cheeses

canned shellfish=mussels, oysters, clams!

canned caviare=try russian/Ukrainian/german grocers/delis read ingredients

canned pates=livery! won't be grass-fed but still good for some liver

canned cod livers

smoked sausages=look at the same places you'd find caviare and fancy butchers/delis. Most important keep them dry. They may get a yeast bloom on the outside just wipe it off with water or vinegar

coconut oil pemmican=may just melt in cali summer but would be perfect for refrigeration like I talked about up top. You can get a one gallon bucket of coconut oil for $40 here http://www.mountainroseherbs.com/bulkoil/a-c.php#oac_coc_u

homemade or store bought larabars

white rice=you may need the carbs!

Insects= the easiest and safest are grasshoppers and wood grubs. Find wood grubs in rotting pine they are pretty big hold the big flat head and bite off the rest. Crickets my description of how I catch them is here http://paleohacks.com/questions/19657/do-you-have-insects-and-bugs-in-your-diet#axzz1Kq9Rqt4I

Most importantly I would say don't let it be to big of a deal. You will be active, outside, having fun, learning/teaching, drinking cleanish water, and breathing cleanish air. So if your food slides a little don't worry just plan on getting back on track when you get home. Avoid the biggies like gluten, sugary crap, vegi and seed oils, and maybe dairy. But don't even stress those if you don't have any serious allergies or autoimmune issues.

Hi static Energy, congratulation for you Camp. Do you know on wild edible plants? I heartly suggest you to get common with that. wild plants a realy nutricious. Another thing is maybe you can dumpster some vegetables and fruits from a store. Then i would look for book and informations on bugs and insects which are edible. Maybe local libaries have good books. Also ask such questions in surival forums or wilderness forum and maybe on www.rewild.info .

Maybe you can friend with the ranger and get some meat of the hunters. Look for the infrastructure in the internet and get the information on the area.

ps. whati notice. most important is water. if you have a good water around. Drink a lot and eat less. If you are tired worked and walked a lot you need to eat. Water get some hunger away let you eat less and is much necesarry in the hot weatehr. and again its summer you can forage such a lot foods. make nettles in all variation. If you get some books on plants you see how much is there to eat. its so much. maybe you can try some herbs or make some jerky. do some traditional native american meat smoking with the kids.

look what local native tribes eat traditionally.

Have you thought about pickling? Pigs feet, eggs, and fish.

Hope you are going to be "tenting" in a bear free zone. Keep in mind the wild critters who might discover your stash and think they have discovered their own "Whole Foods!" Most of what you appear to be taking is portable and self contained but bears can open most anything or cart it off. I lived in a tent for a summer and found it to be one of the most amazing experiences of my life. Now with a bunch of kids maybe not so much! Good luck with all and enjoy!

Tropical Traditions sometimes does buy 1, get 1 free coconut cream concentrate- that could be great to bring along & just eat it out of the jar for quick calories.
