You would almost walk right by this place, as it's tucked away in a residential area with some dilapidated houses nearby. Definitely check it out if you're around, as the artists have some interesting pieces set-up inside.
I'm all for supporting artists, which is why I was alright with spending $10-15 for a visit to the unknown. Some of the pieces were just so so, but some were so impressive. I was impressed with the amount of thought, creativity, and pure labor that went into some of the work. Definitely check out the nearby annex to see a very interesting installation that spans the entire building.
