....so then are the graffiti artists trying to get a grant by writing on walls? If they can afford to buy spray paint, then they can easily afford to by other art supplies.
Funnily enough, just last monday we had some graffiti painted around where we lived (they decided to write some slurs on our trees, so I had to do some trimming). They also painted up every sign post and flat surface (other than houses) they could find.
I don't see a problem with the ordinance.....I don't know of a SINGLE person that I went to middle school or high school with that needed to buy spray paint for any sort of art. I'm pretty sure the majority of under 18 kids don't use any sort of spray paint for artistic purposes, and those that do are a limited few.
