The only bear problem I have had in CO is black bears trying my sleeping bag out. Once during the day which guess was ok since no damage except for new entry into tent and once at night which I took exception to his noseyness. He skidaddled out when I said no thank you. We keep clean bear camp but they are still very inquisitive, nosey and pita sometimes. The key bear issue for you is not carrying but managing your kill site and keeping a pristine clean bear camp. Plenty of threads on LRH on this. Black bears were much bigger pita hunting the Adirondacks then CO IMO. They were more used to people.
