Without looking at the regs I believe CO has a total of 5 general rifle seasons. 3 seasons for west of the front range and 2 east. The longest single season is 14 days from Dec 1 to 14th. Here you can only get 1-2 deer per year. Typically one drawn license and on the plains you can get addtional doe whitetail license.

I would defer to those who know exactly.
