We've seen families from cites encourage their kids to wrie grafeti on buildings in n the Smokies and n rocks etc. They seem to have the idea that the Taggers in LA etcwho put their "art" on train cars and buildings even peoples vehicles are talented and their kids are too. I say from larger cities because as a Country person they are most usually easily identified. Then their are the Latino and other gangs that tag bathrooms across America and rocks and buildings, and even rock in one instance in north Alabama's Little River Canyon. Now that everyone hss a phone it is easy to notify authorities even send photos of them in the act.That is if there is cell service there..but everyoen can tke their photo ora video and how the Ranger down the road or call from there.
