Graffiti I can get behind

Knitting Graffiti in Charleston, WV. How fun? The people in Huntington would probably hunt me down and burn me at the stake if I did something like this. The fountain on campus would look pretty cool with some sort of knitted cozy. Some of this stuff can't be easily removed. But a scarf. How can you object to a scarf? You unwrap it and it comes off. If we could convince all the artists who use spray paint to switch to knitting and then after a certain amount of time send the items to a charity. Who would lose in that situation?
