Wikitravel is trying to do for travel guides what the Wikipedia did for the rest of human knowledge - create an open-source, user-edited global travel guide under a friendly Creative Commons license. But alas alack their entry on Chicago is sort of Pure Suck (I just added something mentioning such obscure sites as 'Second City' and 'The Field Museum'). So go on over and give 'em some help - you'll be furthering the city's good name, giving googlejuice to your favorite spots, and increasing the total amount of public information in the universe. What's not to like?
