I drew 77 first rifle this year as well and will be my first time in Southern CO. Highly unlikely i will be making a scouting trip before season. Buddy of mine hunted 77/78 last year an said to pay attention to motorized/non-motorized areas, especially during first rifle when they start getting pushed from the 2-tracks come opener.
Was also told that water is more scarce than some of the other places we have been in CO/MT with similar elevations and terrain. If anyone has comments on water in the 10k+ range, let us know..... Always too difficult to tell whats really going on from onX and google earth.
good luck and if i get any relevant information i'll shoot you a DM.
