I have worked four years at the company (and 1 year as supervisor), and so we went out to celebrate that anniversary last night. Wandered on to different bars a few times, but at least I got to eat pizza with red beets, chevré, honey, walnuts, fresh basil, tomato and mozzarella... Oh my god. Too good to be true.
I also got to rant about space elevators, possibilities of going to space ourselves, soyuz vs space shuttle, space tourism, the gravity of Mars, and a few other Really Interesting Things when I found a like-minded soul. I think the others were a bit amazed at the energy with which we discussed.
