If you're ever in north central PA, I recommend a visit to Bob Logue Honda (www.boblogue.com) in Williamsport, PA (Home of Little League baseball). Bob Loque has a really nice museum spanning the history of Honda motorcycles. If you're lucky, you might even get to chat with Myron Schroeder, the restoration specialist and former airhead owner.
I've heard of this shop for several years (decades) but never visited until today. It was simply great and reminded me of all those wonderful Mom and Pop shops where the owners & employees knew something about the bikes they were selling. If you get the chance, stop in.
