PA to APG is not bad, about 45 minutes to an hour to delta, southern York, oxford, and some other communities, a lot of people do it,
PA to Mead, fuck that, Mead is about 45 minutes south of APG and you have to go on the Baltimore beltway and a 4 dollar a cross toll bridge. the only way you should consider PA is if your working a flex schedule and work like 4, 10 hour shifts a week, assume 1.5 hours down, 3 back
ATC is doing a big hiring push right now, not sure of your background but there's a lot of interesting stuff here, I am heading overseas for a while but will be probably coming back to area southern pa, MD isn't as bad as people let on to.
another possible option, rent a room for the week around mead for about 600 a month, go home on the weekends, was considering doing something similar for an Indian Head job
