RE: If you could give just ONE tip...??
Hunt where the bucks are! If they are not in your area, you can either spend a lot of time and money to draw them in or you can go where they are.
I hunted deer in Michigan for 30 years before I learned that I had to draw them in with food plots. Now I live in Texas where there are more bucks and a small food plot here brings in more bucks in one season than I had seen in a lifetime of hunting in Michigan.
I didn't shoot a buck last year because the 13 pointer I wanted never offered a shot but my step brother, who had never taken a mountable buck in Michigan took a nice 8 his first day out with me down here.
