That's what I've found too. I watch tv shows, videos, etc. of guys in trees who sit there and watch helplessly as critters pass by out of bow range. Sometimes they can call them in, but most times not. I killed one of the nicest bucks I've taken by getting out of my tree when I saw it at a distance and realized it was never going to come close enough for a shot.... I just circled ahead of the buck and waiting along the trail he was using and was able to get a 12 yard shot on him. If I'd stayed in the tree, I'd never have taken that buck. It's been my experience that if you see a mature buck, do whatever you can to take him......more often than not, you'll only see him one time (or at least that's the way it works most of the time where I hunt). I can count on one hand the truly mature bucks I've seen more than one time....
