Woot! 45 years! Woot!
Well, by this point in the day, what hasn't been said? Go watch some Star Trek. Or read some. Or play some. Or drink something that's unidentifiable, but green. The last few years haven't been the best for Star Trek, but I was there in the drought of the 1970s, and this is infinitely better. (Okay, the 70s weren't all bad.)
So go. Celebrate. And if you'll excuse me I have to go pop a DVD into the Xbox and watch some Star Trek now.
