Welcome to Ticket Tuesdays, a new weekly chance for you to score entry to some of the hottest shows and events in the Bay Area.

Now that the air is crisp, the days are shorter, and ice skating rinks are everywhere, it definitely feels like the holidays. But the Cal Academy of Sciences has made it official with their 'Tis the Season for Science series of festivities that include live reindeer grazing on their living roof, indoor snow flurries, and a special theater show about the Earth's seasons and how animals have adapted to them, inside a dome shaped like a snowman!

Want to experience the seasonal magic? We've got FOUR entry passes to give away, and here's what you have to do: Just sign up for our newsletter below by tomorrow, and we'll choose a winner randomly. The winner will be notified via email on how to pick up his or her tickets! Good luck!
