Rewards from M.D.ing

[N.J.THer]

During the work week I often go out detecting on my lunch hour. Although park hunting is not my favorite thing to do it works well since I don't have any private sites by work. While hunting the parks I always pick up the surface trash as well as the trash I dig. Before I leave I drop it all into a park garbage can. I noticed that I was always tossing a few Coke bottle caps away so I started saving them then entering the rewards codes into the computer when I get home. I just started doing this and already earned two free sodas. Hey it is not much but it cost me nothing.

Does anyone else do this or am I the only nut out there?
