My 3 friends and I are looking at going on a Road Trip this summer, possibly to Seatlle, or if money and fuel is too much of an issue, to hit Austin, TX. We live in Southeast Nebraska. Even cheap hotels get expensive after a while, so what are the laws and etiquete on staying places for free. Truckstops? Wal-Marts? Going off the highway and camping in the woods? What safe/legal/free? Thank-you
