When I lived in Colorado my hunting was down west of Pueblo in the Hardscrabble area and further south in the National Forest west of Trinidad. What Colorado bob said worked for me. Last half hour of the day walked the high ridges and listened for gobbles in the bottoms. A yelp will usually get a gobble if there are any Toms around.

I never hunted around Tarryall but used to trail ride in the Rampart. Saw a lot of Turkey there but it was thirty years ago.

Merriams are all I ever ran into on the plains in Colorado. They roost in cottonwoods along all the rivers out east. The Arkansas, the Purgatory, and so forth.
