Actually the sign is down and has been replaced by one advertising for the landlord. There is a small sign in the window in the last office toward the south end of the hangar. I'm not saying A-Cent isn't there anymore in some form, but it certainly does not present the image of a thriving business. The doors were locked, and no cars in the lot. I should have noted if that air conditioner was on, as it was a hot day. If it was off, that would have been more conclusive. I can't honestly recall if it was running or not.
