I think we're gonna have to agree to disagree here.
I've called them in before, but I just don't enjoy it as much as playing "sniper". I usually wear jeans and a shirt when hunting. We're required to wear blaze orange during deer season, so it doesn't make much sense to me to wear some fancy camo underneath a bright orange vest. I don't get all camo'ed up or sit over a feeder. I still hunt, if you could call it that. I'm a horribly impatient person, so typically I bust ass as quickly as I can over as much ground as possible, and so far its worked remarkably well. 99% of my hunting is on public land.
