i dont bring a chair, i have tractor style seats in my canoe so i dont bring any sort of cushion for that either. im still young (25) so the squatting isnt that much of a bother... yet... for filletting fish, we usually prop the canoe up on some logs/rocks over a low spot so that we can stand and clean fish. otherwise i dont really do much sitting around. im either standing and fishing or sitting fishing from the canoe about 70% of the time. the other say 25% is sleeping and the remaining 5% is sitting around camp. ive been considering bringing a cushion
