Never hunted elk or been to CO (except for a layover).
I can tell you, though.....45 might be a bit crowded.....lol. I KNOW (and I'm sure we're only a drop in the bucket) of at LEAST 15 that'll be hunting there the 18-26th. I'll be one of them.
Good luck to you. I've got 2 buddies with similar questions. I'll forward this to them as it gains legs.
