What is a Flash Mob you say? Well, Flash Mobs are fun, often large public gatherings at which people show up out of nowhere, perform an unusual or seemingly random act and then quickly disperse.

What we'll do is walk around GZ, pretending to be regular, Muggle-type folks until the whistle sounds, announcing the start of the Flash Mob. After 10 minutes, the whistle will sound again signifying it's group picture time. After the picture we'll take off our vests and disappear into the crowd. To finish the event, we'll meet back up at the rest area just east of the Falls.

The idea for this years Flash Mob is to have everyone show up in reflector vests with clipboards and walk around examining or measuring everything. If you have a hardhat, so much the better. Please, no measuring the Muggles. They don't like it.
