I traditionally have hunted mule deer 3rd season CO, which usually works out to be first or second week of November, and have been 100% successful harvesting does. The one year I drew a buck tag, I passed on 3 smaller bucks in hopes of a decent 4 x 4, which I never found. This year I am burning 6 points to hunt a 4th season buck tag in a prime winter concentration area during the last week of November. Based on people's preferences on this thread, it sounds like it should be a prime time to find a good buck - hopefully I can fill my first buck tag!
