Today is World AIDS Day. The good folks at the NYC Student Initiative for AIDS chalked up a bunch of streets in the village to remind everyone that AIDS is still a huge problem in our city-- not to mention everywhere else in the world. Why not take some time to support an AIDS-related charity, learn the facts about the disease, or check out the NY AIDS Film Festival, which opens today at NYU. Are there any other worthwhile World AIDS Day events going on tonight?
