I'm headed to CO next week to bowhunt elk. We came close to success last year but cuz missed at 35 yards. We are on foot so need to know the best pack frame for getting meat off the mountain. We have not found a source for horses to pack an animal out so want to be prepared to de-bone and pack out ourselves. Also, I am flying in so need a frame that adjusts small enough to put in luggage. Does such an item exist?
