This Friday kicks off probably the most moving event of the year, not just because it is wacky, colorful, and hysterical, but because it’s literally on wheels. The ArtCar Fest 2010 will fire up in Berkeley on Friday and roadtrip its way to Sacramento by that afternoon. The fun lasts through Sunday in Sacramento.

I caught up with Costas Schuler A.K.A “The Pen Guy” who created the Mercedes Pens and says riding an art car is a lifestyle.

“This car is an excuse to have a conversation—it’s a context for community,” explains Schuler who says he met 4 people yesterday just at the gas station.

“For me, its an everyday thing. Once you have an art car, you can never drive a regular car again. Where’s the party?” says Schuler who attended his first ArtCar Fest in 2005 with barely any pens glued to it–his car now holds over 10,000 pens.
