I did some shopping today, in preparation for my upcoming trip to Russia. I bought a big new suitcase, since nothing I had was big enough for me to live out of for almost three weeks abroad. I picked up some black & white 35mm film. I love shooting b&w, but it's so expensive to get it developed anymore. You're looking at $13/roll or so anymore. I should probably learn how to do it myself.
I also got enough medical supplies to treat anything short of a sucking chest wound, over-the-counter pills for every situation I could think of, motion sickness, insomnia, fatigue, diarrhea, sprained ankle, you name it. I know I could get most of things in Russia, should I need it, but since you can't even safely drink the water in St. Petersburg, I'm not about to trust pharmaceuticals of unknown origin.
