There were a number of problems;
1). Little or no advertising/marketing. I couldn't find any reference to the event* on Blackwater Motors' Facebook or Twitter accounts.
2). No new beetle. In fact the aircooled beetles outnumbered the recent water-cooled jobs by 4:1. ..and there were only 4 aircooled beetles there, and the water-cooled was probably just in for a service.
C). I was bored within 15 minutes.
* I'm not sure it even was an event, it may be the case that Backwater motors have a BBQ and jazz band on every Saturday, but nobody has ever been there to see them...
