There are plenty of units in Wyoming that you can draw with 1 pref point. someone mentioned above about being careful about checkerboard land. While I agree with that, some of those areas are great to hunt as other hunters typically avoid them. With a map and gps (with land status chip) it's pretty easy to find access points as long as the checkerboard land has public land running through them.
Also, with antelope, I will never understand why someone would pay an outfitter, unless you are looking for some type of record book head on your first hunt. The hardest part of an antelope hunt is not shooting one the first morning.
