Hunted unit 22 third season two years ago for 9 days, sun up to sun down, and I did see 10-20 bucks a day. I did not turn up anything special, but had a great hunt. Of course hunting quality is relative and for a new mule deer hunter coming out West it should be a fun hunt even if it has gone...
You will see a lot of deer in Unit 22 third season. Mostly smaller bucks, but you could find a great deer on the 7 day hunt. Could also get snowed out for several days on your 3rd or 4th season hunt and the longer 7 day season gives you some extra time to make up for any delays. I do not know...
