This BANKSY piece on Washington Blvd and Compton Ave (by the Washington Blue Line station) is still up for you to go check-out. Some real art in the streets. Seriously, though, people have paid hundredes of thousands of dollars, (up to a million even), for a Banksy piece, and here's one you can go look at and appreciate for free, so take advantage of that if you live in Southern California!
Art is important. I don't want to live in a world where art is not important. If that's your vision for a different kind of world, leave me out of it!
