If you're a skateboarder and you've come to Barcelona primarily to skate (and heaps do), MACBA is to Cataluna what the Embarcadero was to San Francisco - a proving ground, a hang-out spot and the site of some of the most memorable street lines to grace the skate scene of late. Ledges, stairs and manual pads for days will have you coming back day-after-day to get your MACBA on, tio. The inside of the museum is remarkable as well (or so I've heard). With all the urban, artistic expression going on outside I never actually made it inside to find out for myself.
