I've been talking with an outfitter about a mule deer hunt in WY. Following is a "paste" of part of an e-mail he sent me today.
"When you fill out the application for deer place a letter H on the line for area and leave the type line empty. Do not place anything on the space for type. For elk place GEN on the line for area and leave the type line empty."
I think he is talking about a paper app. I always apply on-line. If you log in to the WYG&F site you can find and download app instructions which will explain the 1,6, 7, etc. I think I remember that 1 is antlered and 6 anterless.
Hope this helps.
