Probably the AAABA tourney? If so, it has been around for decades and is a special event there. I can't add much more, but I grew up in Pittsburgh, and a couple of times (this was in the late 70s!) we went to Johnstown to see games at the stadium. It was a big deal then. Probably some good talent from NE/MidWest, but if you are looking for exposure (scouts, schools, etc.), I have no idea.
