Good points. I'll leave my last comment in this thread as it has to do with Cedar Fair 2013 and something more than a new show is apparently coming to Carowinds. Once I've had a chance to scout the area myself and get an idea of the scope of the markings I'll start a separate thread. Right now all I've seen is a bunch of pictures close up of spray paint.
Hopefully I'll make it there this week. But first I must be off to Idlewild and Kennywood. I'm also trying to sneak a side trip into Lakemont and Six Flags America (hey, it's *almost* on the way home - just four hours out of the way )
