Definitely get some medic skills, at least learn how to eyewash and carry injured comrades. The Burque Black Cross medic team (homage to portland's black cross health collective) is fairly set on being on the front lines full time. If you plan to be anywhere near the frontlines, bring a gas mask, a helmet, and a life-jacket (floating foam will cushion beanbag rounds like nobody's business).Squats tend to become too hot for stashing in my experience with these protests, it's better to leave the pack with some low key hosts. Come in early, before the police really start itching for something to do, like scouring the bus/train stations. This will be interesting to see what an obama-style police state will be like and if it'll be worse then his predecessor. Learn street medicking if you have to chance, even if you're not planning on being one, since we have a historically high turnover, and I'm retired after doing it for over ten years.
