Don't waste your time looking for Mearn's - their numbers are very dependent on summer rains, which were sparse this year and came too late anyway. Coming off a near-record low population last year, it'll be a long time before they're back.

Gambel's are spotty - where I live (Prescott area) almost no birds in the NF, even the unhuntable inside-the-city-limits quail seem down this year. You should find more Gambel's at lower elevations, but I haven't any first hand information yet.
