Impact? the people you meet as well as the sights and sounds. An adventure around every corner. I tour starting from my driveway, just pedal. make breakfast( oatmeal) buy lunch( a sandwich) cook dinner, grain+ some meat. Not that expensive for some. Stealth camp anyone? Just hang my hammock in the woods. Sure I do stay at some campsites, but not much $, maybe $ 20-30.00. I'm North of Boston, MA and have done most of the state, cape cod, southern NH and going to RI and CT this summer. Beats work or sitting in a car in traffic. Plus earning your beers.
