If you're a registered Democrat or Republican, you can vote in tomorrow's primary. Besides getting a chance to participate in the democratic (small d) process, you'll also get a chance to come face-to-face with one of the new voting machines—no more old-fashioned lever machines, it's now time for newfangled scanners (time for our own Lizard People vote?).
You can find out your voting location here at the NYC Board of Election website. Gotham Gazette has a handy guide for the last minute voter, but we've got some notes on a few of the bigger showdowns if you click through.
