More cover the better.
I like little ground blinds (natural ones) that you can throw a little stool into--especially on public land, where it won't get swiped ('cause you take it w/ you).
Move slow (of course), and don't cover yourself in the darkest camo available--you'll look like a black blob moving around. I prefer lighter greens/greys/browns while on the ground, or camo isn't even necessary.
For real up-close stuff, however, I do find that a little bit of face camo keeps me from being picked off.
And fletching--I don't care what anyone says, bright white fletching will get you busted.
I switched to yellow and red, or deeply barred black/white, and had much better luck.
I try and find something I that I can set up behind, and not in front of, so I can move around a little bit...or even read a book.
But I like to relax out there...so that's just me. I take a stool some water, and a book, and I'm pretty happy.
And if you are still-hunting, I would find a pack that has absolutely silent shoulder straps. There's nothing worse than hearing a nylon scrape every step you take as you're listening in the woods that are nearly silent on a windless day. Drives me nuts...!
Good luck this year....3 days to go!!!
Take Care,
