Long time WarmShowers host ...
I've been a host on WarmShowers for about 6 years and it has been a wonderful experience. Some of my more memorable guests include:
-- A guest who told me about the National 24 Hour Challenge, and thus started my endurance cycling career (his son recently came out and rode the N24HC with us)
-- A family who had been on the road already 12 months - the boys were 4, 6 and 8 when they left Calgary and headed for Mexico. Each morning mom taped their homework to the handlebars on the tandems and tagalong.
-- A couple on their honeymoon, visiting all 50 states and raising money for two fantastic causes
-- A photographer/touring cyclist who I am still in contact
And many more.
I recommend everyone consider becoming a host, whether you live alone, as a couple or a member of a large family. And regardless of whether you have just a small place to pitch a tent or a private bedroom w/bath.
