Last year, I packed a decent sized forky Mule Deer from a ravine at the bottom of a 60 degree slope about 7 miles through a series of ravines and finally about 3000 ft descent. Everything , one trip, all except the last mile off trail, through brush, thorns, oak brush, some class 3 through rock bands, 800 ft uphill at one point. Pack weight at home was a bit over 90 lbs. I took one small break, when I slipped and thought "this is nice place for a break". Moving time was about 4.5 HRS. Honestly, I felt pretty good the next day and likely could have done it again, just slower. However, that being said, I would not pack a bull from the same spot without some packers ready to go, even if it was an 8 X 8 and cold enough to take 3 days. Would I take another deer there ? Probably not, I know of areas closer that hold some nice deer as well. I felt silly putting that much effort into a non brute, even if he eats fantastic.
