Re:I could be wrong but...
It is doubtful you had a workshopr with Erik about 20 years ago. He's probably in his early to mid thirties, which would have made him about 15 or so at the time. He bought the place from Charlie's sons, thus the name. Their dad originally owned Charlie's in Kenilworth, if I'm not mistaken.
Yes, Charlie's opened a place in a small strip mall on Route #22 East in Union. I have not been there, yet.
