I picked up a couple with my van in Nov. as they would never have found my house
Gave them a shower and room and ordered them a pizza. took them to a supermarket, gave them computer use
and got them on the road in the morning. I have had hosts cook for me (this I didn't expect) and give me a room and shower.

All I ever expect is Thanks and I have treated my hosts the same. I do send Thank You cards to my hosts
