You have to draw for a tag before you can apply for the permission slip to hunt in some PLPWarea'sbut some areas are just walk on. I went on a lope hunt this year and the ranch I hunted on parceled off a bunch of his property to the state for walk on hunting. Three guys hunting on that piece got goats. I watched as the same goats I paid to hunt ran over and under the parceled property.You have three chances to draw (I think)different zones, look on the Wyoming site to see what zone's have PLPW land and also the highest draw success from the previous year. Here you go, http://gf.state.wy.us/wildlife/access/plpw/index.aspif this is more than you wanted to deal with then there is option #2
If worst comes the worst there are booking agents that have ranch contacts thatcan get you a tresspass permission slip for about $300-400 in SEWyoming. The trick is to find these spots where therelittle to nopublic access, this is what gives you the greater chance at getting permits. When I was out theremost locals will not give this info up for obvious reasons of courseGOOD LUCK!
