Phil and I have taken some heat in the past for discussing SE AZ quail hunting on public forums. Especially in low bird years, the extreme pressure will move the remaining Mearns to less desirable habitat. Gardner Canyon road off 83 looks like a California plate parking lot in Dec. I was hunting near Greaterville yesterday and had 3 vehicles drive by my spot, and met 3 more on my way out on FR 229. Part of the problem is that access to the Coronado National Forest west of 82 between Sonoita and Patagonia is mostly through private property and strictly limited. Lots of pros winter out here and several times I've seen quads loaded with a guide, 2 hunters, and a 3 dog box.
2 nice threads by Walt Lister here about Gambel's hunting north of Wickenburg with pics of the country

http://www.picturetrail.com/sfx/album/view/21096662In a good year, a fella could harvest all three quail in a day. Gambel's are found in the prickly pear on the northern (lower) end of Las Cienegas, and as Richard said, no cholla above about 4000 feet. Keep climbing (south) to the oak canyons for Means, then back down into the big grass for Blues. You can access the south end of Las Cienegas off Curly Horse Ranch Road, and work along the private ranchettes.
