Now, Fleet Week's cool with the ships and the planes and the firecrackers and all, but SFist's got penciled into our calendar two events of note: the Robot Fighting League Championships at Fort Mason (all the good stuff is at Fort Mason these days) -- and the "Community Disaster Preparedness Faire" on the Marina Green. What exactly goes on at a celebration of disaster preparedness? And more importantly, why is there an extra e on Faire? Are we to assume that it's going to be a medieval community preparing for disaster? Will there be chain mail, catapults, and dig-your-own-moat kits? Can the Essefficist look into this, please?
