Or, you can be a broke-ass cracker in Appalachia - although most of them aren't much into hiking if there isn't a trout pond at the end or they're actually driving deer...
I could theoretically just hike my way off to somewhere to hike. Land use laws are different, and as long as I'm not messing up someone's forest, I'm good. And public transport will get one closer.
Indiana, most of those ponds and hunting places were state parks or privately owned places with "no trespassing" signs up, and far out of the way of the city.
