I reckon good grafitti only crops up in like densely populated places like cities and stuff.

Most towns have grafitti artists who are just groups of pikeys who do it because they think it's cool to ruin things while smoking cigarettes. In cities, you either get big groups of gangs, or/and actual talented people who get a kick out of spraying awesome pictures
Just a guess tho.. o_O
