I hunt with selfbow, and found that carrying blinds, seats, stools, etc... is not for me. I am starting to use mobile blinds,like Asbell talks about. He mentions using a screw in seat called Cross Creek tree seat. He uses it, more or less, to just lean against to take the weight off his feet, for priods of time. Does anyone use this seat, or knows of a company that makes something like it? Thanks
