I have my local public art tour set up through a DIY tour site (set up a tour in your city) called Vayable.com. They just moved offices a block away from CELLspace and the murals that I try to maintain and curate. Hard to maintain and curate with no budget, but I make it happen via profits form the tour and an amazing group of volunteer artists, builders, and neighbors.
I walked June from Vayable through CELLspace last week and gave her a tour. She made a short video of the visit.
