This past week I had my first experience hosting some cross-country cyclists for a night. Quinn, Ken and Andy are biking from Portland, OR to New York, NY and came through Indiana, riding into Richmond on US-40. I recently became the sole human occupant of a house with great space for hosting guests, and so I figured the least I could do is sign up for some opportunities to help out folks who find themselves on interesting journeys through the area.
WarmShowers.org is a resource for facilitating just that for cyclists, and it's a great way to find or offer lodging. You can provide as much or as little information about your location and "amenities" as you want, and you're under no obligation to host anyone at any particular time. It's similar to other resources like CouchSurfing.org or even Mennonite Your Way.
