Ramp It Up: Skateboard Culture in Native America (National Museum of the American Indian) is kind of a sparse little collection but it’s definitely interesting, and it includes some really cool photos and decks.
That skateboarding is rooted in surfing is a huge part of the exhibition, and they’ve even got a signed 33″ Larry Bertlemann – where else can you find one of those?
Go see it sometime before June 27, 2010.
