I will be traveling for the next few days, so there won't be any updates until next week. But before I go, here's a link to one of the strangest articles I've found on the internet. The article, from The Bulletin of the Atomic Scientists, is about a group called "Diggers of the Underground Planet," who explore the tunnels under Moscow. Here's an excerpt:

"Under Bolshaya Pirogovskaya Street the Diggers discovered a deserted laboratory with an old telephone, chemical-protection suits hanging on the walls, and old-fashioned respiration masks. The room appeared to have been abandoned in a hurry. In adjacent rooms there were huge flasks, and the floor was covered with crystals."
