Probably not going to be decided until April/May of 21.
I've been waiting on a few, and have been trying to predict a few. Not sure if it helps you much.
**MY GUESS** given recent trends and trying to schedule all the seasons:
Elk (westside)--
Early Muzzy Oct 2-8
Modern Nov 6-17
Late Muzzy Nov 24 - Dec 15
Deer (blacktail)--
Modern Oct 16 - 31
Late Nov 18 - 21
