My anniversary was January 3 (it opened in Albuquerque on New Year's weekend, and I drove four hours one way to see it)... I celebrated by going to the full moon chat here.
I bought a ticket to see it January 6 in Albuquerque, before the powers that be decided to expand it faster... I've still got the unused ticket.
And then on January 6, it actually opened in my dinky, no-account mountain town! (We were a test market, yay! Probably because our local theater chain also runs a theater in Laramie. Plus some of us e-mailed the theater chain, um, multiple times, from multiple e-mail addresses, wanting to know if they were going to show it.
) So I've also got a ticket stub from January 7, when I saw it for a second time.
