Nothing is going to happen if you don't post comments on warmshowers positive or negitive.
Historian, I have the warmshowers name of the 2 "cause" riders, if you would like to post a comment please let me know. My apologies since I sent them your way but they seemed to be pretty decent guests when they stayed with me. But post stay I had kind of mixed feelings. I had asked for their picture taken on the Montour Trail and never got it from them. I think that is little to ask for a two night stay. I have a contact for them in India and I am not going to forward it to them.
BTW feel free to post a comment on staying with me on my warmshowers on your stay with me. But after reference of the cause riders, maybe I would rather do not post anything.
But people please post those comments positive or negative on hosts and guests. It is probably not a good idea to agree to host anyone without first knowing their warmshowers name.
What I like to do on tour is to bring several refrigerator magnets from Pittsburgh. They are small and light. I give one to someone that goes above and beyond to show me a kindness. Not much but a nice little token of appreciation.
