Consider your working within the confines of about an acre. I grew up were we had one acre of manicured lawn and a few acres of woodland. We made trails, hung out, and generally just spent a lot of time in the woods. I've always found our efforts to manicure lawn and "keep a yard" kind of weird. Like a perverse sort of control freak thing in a way. Especially when you go chem lawn green.
How would you/could you emulate free form yard and nature in a suburban atmosphere with only one acre without completely freaking out your neighbors? Any links or books on the subject? Could you ditch your lawn efforts all togeather? I was just thinking plant a ton of trees and let nature take its course, but would you need to consider cultivating the undergrowth?
And of course consider wild fruit, berry and other self perpetuating vegetation would be a huge plus.
