There are eightysome other Yuri's Night events all over the world, even some in Antarctica! Link to list, find a party in your town and schmooze with space nerds. In some cities, NASA astronauts and other folks who work with the space program will be present — I imagine that will definitely be the case here in Houston.
Live chat and party photos from around the globe are already hitting yurisnight.net (Link to full list), and here's some from Cape Canaveral in Florida. Also, you can tune into webcams for streaming video from different cities. I'll be hosting the webcast for Houston. See you online!
