The Guard and the Active Duty AF are two different beasts.
I won't go active duty AF right now, but I am pledging Guard units (and doing the Navy thing)... From what I have seen and heard the Guard is still okay if you get into a state with strong congressmen. Units like Fort Smith, SC, Burlington etc... are going to be around for a while. FWIW my old man was an AGR guy for almost 27 years in the Air Guard. Even though his last tours were at ACC at Langley he still deployed with his unit (Syracuse) on their rotations to the desert.
