Here's an event TOTALLY worth checking out, near Lancaster PA (Ephrata, specifically): American Legion Motorcycle Show http://amlegion429.com/special_events I went there last month and it was pretty awesome. While the page says "thousands of motorcycles on display" there were "only" hundreds when I was there, but the weather had yet to break. In nicer weather (like May 4!) I won't be surprised if there are really thousands of bikes there.
