It's a wonderful day to get more philosophical with people. You have the time you need to share your ideas, and there are more than a few people in your crowd who are eager to debate some recent events and controversial issues with you. Even if the tone of the talk gets heated, you won't have to worry about anyone losing their temper or getting personal. So test some of your theories by tossing them out into the group and seeing who can tear a hole in them (if anybody can!).
