Damn that looks awesome. From time to time I like walking around and taking pictures of murals and street art. Looks like I should come visit you.
Here's some of the stuff I've spotted around town. I need to go exploring more :D.

I'm really keen on that Reign piece.
And when I went to SF earlier this year, there was some great work near Ameoba Records

Cinci is a great graff city.
I went to Scribble Jam for many years there and watching the graff artists put up their pieces ended up being my favorite part.
