Military Info
If you want a tour of any base, call the base operator (the Air Force still has these; the Navy mostly does not). Ask for the Public Affairs Office, and explain you are interested in a tour of the base.
They are happy to oblige, as that is their primary function. They may ask for what purpose--tell them you are interested in a career in the military.
If you want to be a pilot, do not talk to a "recruiter." Traditional recruiters are signing up enlisted troops. I never found a recruiter who would willingly steer me in the direction it took to find out how to become a USAF pilot.
If you visit either Phoenix's Guard Unit, or Tuscon's F-16s, ask for a tour that includes talking to pilots--a Guard unit will probably find some time with the full-timers, such as the Commander or Operations Officer. They can help with more details. A Guard unit may not have an phone operator; try Operations if it is in the phonebook.
By the way, Davis-Monthan has A-10s, active-duty. The F-16s are stationed at the Tuscon civilian airport, at least, they were for as long as I have known.
If you are thinking active-duty, there are three ways to be a pilot, but only one option for you (since you have finished college, the Air Force Academy and ROTC are out). You are in a good position to go to Officer Training School, but right now, pilot slots in OTS are very limited. Look up Air Force OTS on-line and you could probably find some contact info.
Good luck!! Being an Air Force pilot was the smartest thing I ever did.
