My group and I are flying in this weekend to do some canyons and really want to practice our pothole escape skills. Sadly, it appears that potshots are sold out (if anyone knows of someplace I can get one one, that would be great). Anyone have recommendations for improvising them? I'm considering a heavy duty dry bag with some cordura gorilla taped on for durability, but I"m not sure. Otherwise we may just try to make do with pack tosses and team climbs. Thanks!
