they call this art, but i find a spray-painted trail off a jumping-jesus-in-a-sequined-jogging-suit almighty awe-inspiring peak like that far more beautiful at the end of a drug-addled/sun/stress/aerobic-assassinated day
it's art, as you say, so i'm prepared to be a classic, middle-of-the-road weenie, and not get so all-fired up about it that i'd challenge a random stranger to an inter-webs death match over it, see?
that said, were i w/ homeboy who did this, and obviously thus familiar w/ the descent route, i'd probably voice an opinion opposed to it, but in the end, not squawk so loud so long as it didn't keep us from the beerz n' bitches for more than a few...
