As it says this is the 2'nd year for this event. Yes, it's mainly V-Twin customs and choppers however we had a good number of vintage bikes there too. I even won a trophy! With the addition of cars the crowds should be even bigger and the venue is larger too. The sponsor, Vampire Cycles, is a good shop, not brand specific, builds custom bikes and services all makes.
Here's the show's web site which includes links for bike entry/registration forms.
