After a week of researching street art in Amman, my eyes are constantly on the lookout for graffiti and murals. So when our group embarks on a road trip to Wadi Rum and Petra, it’s impossible not to notice the stray graffiti here and there on the side of the road. Even as we get into remote stretches of desert, the occasional structure that pops up is almost always tagged, marked by someone’s spray can. Only once do I see graffiti at the base of a rocky mountain. I add a note to my mental list of the unwritten rules of graffitiing: don’t vandalize natural structures. This proves true in Petra, where street artists have repeatedly tagged the little shops and stands that dot the long hike through the wind-chiseled rocks, but not the rocks themselves, which are already streaked with color. Near the top, just a few minutes from the monastery, I have to laugh when I see a tag by an artist I recognize – SINER, one of the most prolific graffiti artists in Amman.
