Food for thought.... ART vs Bum
As a bum you are accruing points toward retirement. Also, for every 90 days of MPA you are getting your retirement 90 days sooner than 60.
As a ART... not so much. most of your time in squadron is civilian. unless you plan on retiring as a ART, you get absolutely no credit for all that time in the squadron (except reserve days). I bummed like you for years and got to major (without regionals). Now, I also get my retirement at 55 and will have close to 5000 points. Best thing I ever did was bum looking back.
IMHO, If you don't need the $ and steady paycheck, I'd just keep bumming. Plus, ask yourself, why are there 200+ ART positions empty and starting in Dec, UPT grads are going to be FORCED to fill them for 4 years (a complete other discussion).
