I did an archery elk hunt in New Mexico a few years ago. I hunted the Gila NF in Unit 16A. It was the most physical arse beating I've ever put myself through. I got a decent 5x5 on the final day of the hunt. Hunting the bugle is cool and if you have a chance you should check it out. My advice is to get in shape. If you are not in shape your likelihood of getting an archery elk drops by 75% IMHO. I was running 3-5 miles a day for 6 months leading up to my hunt and the altitude still wore me down.
I def want to do that one day but no way my dad and FIL could do that. they are in their 60s and couldnt take it, thats Why I wanna do the GUided rifle hunt
