I wouldn't go there if I were you, least of all during 2nd season. Too many hunters, not enough elk, tough terrain and vegetation to hunt them in, poor success, poor trophy quality, etc, etc. It's a popular unit more for convenience and proximity to the Front Range than because of any special quality. I don't like the Flat Tops either, but at least there's lots of elk there and high success rates.
So sorry, the right direction should be a better unit.
And I guess since you wanted tips on where to go, either go North into North Park, west to the Gore Range, South towards Vail and South Park or East to the good limited units on the Front Range like 20 or 46. I also wouldn't hunt 2nd season.
Bring them in on a string. I love this term, if you want to be successful on calling in Elk, try not to just sound like the other caller. We all laugh at each other when we are practicing Elk calling at home or while camping. When I first started calling in Elk, I had no idea what i was doing and it's funny how many I could call in. The biggest Bull that I have called in to date was actually my first. I was making cow calls and screwing it up big time. But it's obvious I didn't screw up...
