1st thing I do is look at drawing odds, PP or not you want the best odds, 57 type one will still be hard to draw, but across the road in 53 you got better odds. how much time do you want to spend on it. Alot will depend on how much rain we get early and if we get rain when your hunting. one day you maybe on the only water for 20 miles and the next there water every where.( this is when a 4x4 w/chains can come in handy). You need to have a back up to the water hole thing. A decoy or a plan for staulking. I have no dought you'll have chances on P&Y bucks.
My son drives between Cheyenne and Pinedale 2 or 3 times a month so I can keep you posted on the conditions.
do some home work and pm me. almost all the areas will give you a good chance at one that will book.
