It’s totally possible, and it seems that a group of competent writers can get an entire building done in short order. There’s no reason to waste time trying to get the management of one building change its mind or to punish the owners. You find 10 others that agree with your goal already. The public has your attention, use it wisely. A group of Australian taggers show you exactly how easy it can be. Run around, have fun, and film it in HD. Way better than bitching on facebook, and it was just for a spray paint brand ad. We can do better. #rip5pointz
