I used a blue plastic tarp which I cut to fit. It worked very well. The most crucial time was while camping at the Knott County Historical Society in Hindman, KY I chose to stay in the tent that was already set up. My ride partner did also. I used my home made footprint as an added shield under my sleeping bag, and my panniers. My partner elected not to use his. It rained very hard that night. The floor of the tent leaked badly, I stayed dry, but my partner was soaked. My footprint doesn't weigh much, nor does it take up much room.
