I guess what everyone is saying is a "goody bag." It can be filled with 1)hand cleaner (which I have gotten, used and loved, 2) a ride patch (to commemorate the ride), 3) a route holder (I've gotten these at rides as well - its a little velco device that fits on the handle and holds a route slip), 4) sun screen or lip balm is nice and also 5) something nutritional like a Luna Bar or something. I must rather have these things instead of another t-shirt. But definitely want a patch as a keepsake of the ride and date.
