The semi-unofficial Chicago 2010 PPC Gathering took place on September 7th and included Tungsten Monk, Neshomeh, Phobos, and TM's little brother, who was dubbed Agent Isotope. This Gathering occurred purely because the PPCers involved happened to be in the city at the same time, and was not announced to the Board ahead of time (hence semi-unofficial). As with the previous Chicago Gathering, the crew spent the day at the Field Museum of Natural History, where they encountered time portals, dinosaurs, shrink rays, and suspicious Flowers.
The Gathering report can be found at Phobos' LiveJournal.
