Looking at the list in your signature, has sort of got me thinking...but if you have the room, money etc. I guess it's ok. I mean bikes are large when compared to somethings people collect such as figurines. You could easily put 60 figurines in a single cabinet...sixty bikes on the other hand just starts to look crazy. Then again, 60 bikes may not look so crazy if you have a 5 car garage and only 1 car!! It's all relative, right?
