arroyobuck,
legendsguide knows that country pretty well and could tell you better than most guys , hes out there pretty often.
On the down side , I've been fortunate enough to hunt and go with friends who also drew unit 2, but they were all rifle and bow hunts, and have had great hunts. The muzzleloader hunt is tough , as mentioned above , its a migratory factor unit , once southern CO gets some winter weather , unit 2 loads up. Your hunt is in Sept and its still pretty warm , but like I said , legendsguide can tell you better , I'm sure not ALL the bucks go north into CO, theres still has to be some deer ...
