How do you know it was a mature buck? Did you see his body or just his rack?
The first thing I would do is figure out the prevailing winds for that day. He may only bed there on specific wind directions. Next, figure out why he bed there. Can he see/smell danger approaching from all angles? This will help you locate other potential bedding areas on your farm.
Also, I wouldn't hang a stand right over his bed. I'd hunt along one of his trails leuote]
I got a good look at his body and rack. He ran from left to right. When I say mature I meant at least 3 years old.
He was only bedded around 20 yards from the edge of the field on a rise. I'm assuming he was keeping an eye on the field for does or because of the high winds.
Finding bedding areas is tough on our farm. When my grandfather had it logged years ago, they cut every tree above 14 inches in diameter. The whole farm is big thicket. The good news is that we seem to hold good deer, but it makes finding them a little tougher.
