In 2012... I'm planning on leaving my Westbrook, Maine home... Cycling down to Yorktown, VA, and cycling the Transamerican trail.

What I'm wondering. Is how much should I save? I'm not planning to bring a grill at all. So I'm going to be eating cold foods, fruits, sandwiches, etc... I'm also planning to stealth camp as much as possible, and staying at some places listed on Warmshowers.org. I'm only going across country one way, and I expect the trip to last 45-60 days. So with that said, How much should I save? I hope to get respondes from people who have done this. I'm sure there are other expenses I haven't thought about!
