If there are very few water holes in the area, your best chance for success will be setting a ground blind near water and wait, and wait, and wait.. If there is a water hole every 1/2 mile, than all bets are off on that tactic. Next best thing would be use of a decoy, but the rut needs to be in full swing for that tactic to work at all. Then there's the spot and stalk, which is tough at the least. If there are enough hills, ditches, drainages to break up the lay of the land, this is a possibility. If the vegetation has some taller stuff like sage brush that can be used, then spot and stalk is the way to go. Carry plenty of water, because you'll end up spotting one way over there and going after it, then when you blow that stalk, you'll spot another one way over that way, and then go after it, and the next thing you'll know is that you're hot, thirsty and a long ways away from the truck.
I killed a nice buck two years ago and a doe last year by spot and stalk. There is too much water in my area and just enough vegitation and breaks in the lay of the land to allow me to have success. It was the 9th day of my hunt when I got my buck and only the 3rd day last year to get my doe.
Good luck. It's a blast becuase finding them is easy, so you're always in the game.
