A guitarist/songwriter friend of mine is considering doing a series of short tours this summer, playing mostly coffeeshop/bookstore gigs while seeing the country. His plan is to take a leave of absence from work and live on savings, taking a couple weeks per jaunt with a week of home time between each leg. The only downside is that he doesn't exactly have a friend in every city whose couch he can crash on after each show. Has anyone ever done anything like this before or know someone who has? What would be some suggestions for a jaunt like this?
