I spent last year in Colorado's units 18 and 37 2nd rifle season trying to learn to hunt mule deer. I.ve never been there before and didn't know where to start. I got boots on the ground and found what i thought was a good buck and took him home on the second day. My original plan was to backpack way back and spend time glassing but after i located my buck near my camp i couldn't be persuaded to go further back. I now have ?'s. What is a mule deers preferred habitat ? Should i spend time in the "High country" for 2nd rifle ? Should i be looking more in the dark timber ? Is a 4th rifle season a better opportunity ? for GMU 18 37.
