One note of caution to our ever growing and enthusiastic Minions and Legionnaires, you might want to check local tagging laws to avoid any un-necessary conflict with the local constabularies. Sidewalk chalk on sidewalks does not normally lead to much more than occasional irritated language, but it might be worth checking first about your area. This war against "Normalcy" is not yet in need of any true martyrs just yet.
Send us photos though. We will be more than happy to post them here and credit the source!
