Castle Hill, topped with the old Texas Military Institute (TMI) “castle” has been around since 1870. “Grafitti Park” below it, though, is a 2011 South By Southwest (SXSW) art exhibit that has obviously been wildly popular. Visitors are invited to bring their own spray paint and paint away. Even though David and I both went to law school in Austin, we were surprised and intrigued to stumble across the graffiti-covered park while looking for a parking spot the past Friday near favorite restaurant Wink. With the sun sinking low, lots of people clambered over the brightly painted walls.
