Last year was my 1st time elk hunting in Colorado. Myself and 2 buddies went. I did most of the e scouting and data analysis to decide on what units to hunt. Our plan was very similar to what you are suggesting. we where planning on doing 3-4 day trips with camp on our backs. Due to weather, extreme storms in a few units. we had to change plans and did shorter trips but still went in a few miles one way. Toward the end of the trip we had an area in mind and started to hike to our camp area 2 miles in. We where always bugling while hiking looking for a response. on the way in about 1 mile from the road I bugled in a bull and my buddy shot him with his bow. While butchering the elk, another bull was bugling around us so, we decided to make 1 trip out with all the meat. We wanted to be able to hunt there in the morning. 2 of us had 1 hind and 1 front quarter and the last guy carried the head, cape and loose meat bag. It was a hard mile out but we made it happen. Not bad for three 40-plus year old's from Michigan!
