Think you need to be more specific on what your looking for in Colorado? Are you looking for a Outfitter, Drop Camp, Self Hunt?
Far as a Outfitter, thats the route I took last Sept. on my first ever trip to Colorado. Its probably the best way to go if you've never hunted out west like myself. I went with Winterhawk Outfitters. It was the hunt of a lifetime. I had a blast. They do a western style hunt using horses & mules to get you out of base camp back in theforests to the Elk.
