remember stealth too. Don't walk into a roost areaand start making a lot of noise setting up a blind at a feild edge. Also if you have to break a bunch of branches in the timber to get it into place it probably tells you sittng down against a tree is better. I think set up wise you're looking at 2 things: open areas, expected long sits in one place.

I guess I add weather to that. Regardless of where I might be going if it's raining it keeps me focused and out longer if I have my blind. I just make sure to be as stealthy as I can getting set up. There's a lot more to that with a big blind and a chair.
