On the west side of downtown Austin, nestled in the Castle Hill neighborhood lies an abandoned lot that I never knew existed until our trip down for SXSW this year. Locals have called it the Castle Hill Graffiti Park, or the Austin Graffiti Park, but it's official name is the The Hope Outdoor Gallery Project. And unlike your typical city park, it's a rough and hectic series of abandoned walls that serve as a 3 story canvas and playground for graf-artists from all over the world.
