There's street art and then there's graffiti. One can be beautiful, creative and inspiring; the other can be destructive, ugly and a huge nuisance. But the dividing line is difficult to determine. For proof of that, just head to the front of the graffiti war: Sheridan Boulevard, where you can see how two different cities are fighting this problem. Sheridan borders with both cities from Colfax south to Yale. And if you take a drive along this strip, you'll quickly recognize that graffiti and tagging are an issue here. Look a little closer, though, and you'll notice that the east side of the street is more marked up.
