you will loose any points you have if you dont apply or buy points for so many years. I forget exactly howmany. WY is broke down into regions and limited quota units for deer. The regions are basically a group of units managed together. Antelope are all limited quota units. The Wyoming MRS explains it all pretty well.
I believe if you do not apply for 2 consecutive years you loose them.
Wanderer, One thing to keep in mind is your opening dates for antelope & mule deer (Rifle). Unless you plan on archery hunting. I've done the combo hunt several times (mule deer/antelope). We always done Unit 7 antelope & Region B Deer. (Rifle opens October 1st)
