I recently did some training at the SAC location. Overall a good facility- the instructors I flew with were all sharp and knowledgeable. ATP is actually the largest school at SAC.

SAC has a nice practice area to the west, not too busy. You'll talk with Travis Approach and Sac Approach often. There are also several uncontrolled airports in the area. It can get windy, but that's just good opportunity for crosswind practice.
