Front range of CO is a tough nut to crack, not many birds, tons of miles of land lots of city guys doing exactly the same thing in the same spots. Any place with decent hunting is a draw, probably for good reasons. The few times it worked out for me (before I learned to go to better spots) Ponderosa slopes with oak brush and some cottonwood creek habitat were where the few birds spent their time. Holy crap do they cover ground, tracked them for 8-10 miles in a day pretty much straight line travel. Very little gobbling is the rule, but Id guess this is mostly from the lack of bird densities, when it worked it was great, didn't work very often! DRIVE... best advice you'll ever get!
