I think it all sounds like a great idea - one I wish I could pursue, but life's responsibilities (not all of them bad) gird those freedoms sometimes.

At any rate, and I don't want to sound flippant or condescending, but I've seen this thread for a few days and it keeps making me want to reference Into the Wild. Not so much as a cautionary tale, but more because the dreams and desires seem related. If you haven't read it, check it out. Also, it may in fact make you think twice about how cavalier you are about not having a plan and being adequately prepared.

Hope it all comes together for you!
