I think i would have a lot of doubt,at 20 years old he would't have a lot of experence but would have a great amount of stamina which is a lot of elk hunting,but those years of knowing where the elk are would be is kinda doubtful.we had hunted a area for several years and a new guide took over and we recieved the young guy for our hunt,he knew about elk and their habits the only thing he didn't have was the experence of the local area which to me is the most imporant reason in having a guide.half of the time he didn't know where he was at and the half he was asking us where we were at.not that he was a bad guy he just didn't have the experence.
