You can plan hunts 5 years in advance in Colorado.
Just go to the DOW websiste and go to their search and type in '5 year big game season structure' or '2010 big game season' or something similar and the 5 year schedule will come up. The seasons are NOT set in stone, so the dates COULD change a little as time goes along. I had a link for the 5 year plan but have lost it or I would post it. I'll look when I get to my home pc on Sunday and see if it's bookmarked there. Good luck.
I am not trying to argue with you TennVol, but I know that Co does hold a certain percentage of tags just for resident tags and only around 30% goes out to Out of State hunters so if they give out 2500 tags only 750 will be allowed to the nonresident hunters. I agree he shouldnt have any problem drawing one, my daughter which is resident didnt draw her 1st season tag last year (2007) but everyone else did in their group. It takes every other year to draw a 3rd season buck tag, I love those pref. point systems every state should have them
