Hunting Colorado is largely a matter of how many preference points you have. Colorado DOW has statistics available on their web site that will help you figure out what units you may be able to draw. This should narrow down your choices quite a bit. Once you have done this, and figure out which season and weapon that you want, you can get some useful opinions here.

I hope you and your father are in excellent shape with no health issues before you head into the high rough areas!
