Welcome Cushka, where in Pa. do you swing that coil? I'm from Ohio but worked all winter around Washington, chasing down broken industrial heaters on oil and fracking pads. Those service calls took me on hundreds of miles of back roads, some just gravel two-track, and there were TONS of old places along those out of the way routes, some appeared Colonial. So good luck out there, welcome to the club and we're looking forward to seeing some of your good finds posted. Ddf.
