Basically if you eat grocery store food (or better), that is what your body wants, and it costs marginal zero, since you have to east something. It probably is more expensive than that because some foods i prefer to eat on the road like say a peach, I might actually be eating something cheaper like home made bread if I was at home. And as far as sleep, if it is wild or stealth it's free.

But if one ramps it up even marginally, it gets real expensive around here. I am visiting my parents at the moment. My daughter and I stayed in a motel, and it cost 70 for one night. I would like to say how nice it was, but it was bottom of the barrel, that doesn't have roaches. Campsites cost 35, and they may well be worth it, but that is what I would prefer to spend on Motels if I could find it (I mean I prefer camping, it is just the lower price I feel I should be able to find).

The idea you can eat anywhere for 4 bucks without eating the kind of crap from Super Size Me, or dumpster diving, is pure fantasy. I just said the kind of crap, you aren't getting out of McD for that. People pass on their best day ever like it was normal, they also average 20 MPH.

The complication I have is finding wild camping, etc... in the same kind of place I find easy access to decent food. Going past a large market every day, usually means area build-up (small markets around here are just convenience places, they don't have food). But getting easy access to nice wild camping moves in the opposite direction. That is what I prefer about kiking and boating the opportunity to go all wild. Around here you can do that on some snowmobile trails also by bike, but usually only pretty short trips. Any day out is a good day, but it can be expensive. My favourite areas to bike tour around here have decent food access and pay camping, but that is 35-50 a day. Over several weeks that ads up.
