I decided to move my trail camera out a lot further. About 3 miles from the nearest road. Where overgrown laurels give way to steep mountain side. Maybe the bucks are hiding out where nobody wants to go.

I agree with the hot weather and low deer movement, along with a change in preferred food source possibly being the problem. It seems to be very hit or miss. Either you found all the bucks or nothing. I would not worry too much about it, everything will change soon when the bachelor groups all break up. Good Luck
