Whenever i draw my bow back i have made it a habit to always completely open the hand i hold the bow with. The pressure from the string being drew back obviously holds the bow in place. Then just befor i release i relax the fingers so they just barely hold the bow. That usually insures a relaxed grip so i don't tweak it when i release.
It's pretty much impossible to not point my trail cam in a direstion that the wind won't blow everything around in the area i'm hunting. Guess i'll just have to wait till the corn comes off, i'm sure i'll get a lot more pics then. Or better yet, wait till after Oct. 1 and sit in the stand and see it for myself!!!
Good luck guys! It's gettin close!
