I second interest in the ANG.

No offense intended (really), but I'd avoid "sending" your basically-an-adult son anywhere, to include an FAA doc. Show up at a Guard unit WITH your son, and you run the risk of scaring the unit that he's not mature or independent enough to handle the challenge. I've hosted many an inquisitive escorting father at multiple Guard units, and it doesn't usually bode well for the son/daughter's potential. Maybe it's today's standard of parental involvement, but it seems like your son should be the one on discussion forums investigating his own future?

Good luck to you both!
