PowerHouse is :
on Edsall Rd. just north of the springfield interchange.
(if you are going 395 north, take the second Edsall exit, if you are going 395 south, take the first Edsall exit ) i can't remember which is east/west - A/B sorry
anyway, take your first left (across from the gas stations) to head into the industrial park. after about 1/3 mile, you will go over some RR tracks. Look for a road that peels of to the right just after the tracks. once on that road, go about 5-600 yards, and you will see PowerHouse on the right.
(there are a bunch of 'shops' there on the right, including Dunbar and a few automotive shops . . .)
i have no idea who is running the place anymore, or i'd tell you who to ask for . . .
(BTW, Faux -> i heard you had yourself a Works . . . True ?? if so, how do you like ?? )
