Wikipedia Takes Nashville was a scavenger hunt and free content photography contest aimed at illustrating Wikipedia articles covering the sights of Nashville, Tennessee.
The event was held on Saturday, May 24th, 2008, and ran from noon until 8 PM. Everyone checked in at the starting point in front of the Parthenon at noon, ran around the city like mad taking pictures of all the goals, and then met back at 8 PM at the 3 Crow Bar in East Nashville for the after-party. The winning teams were announced that night.
This event was inspired by Wikipedia Takes Manhattan. So they get all the credit for coming up with the idea.
