Heard a press release today about Wikimedia Argentina participating in a photo scavenger hunt, similar to the "Wiki Loves Art" event that WM NYC has done in the past. More evidence that the activity is really a great idea, and there is so much potential for Wikimedia chapters to get involved with local museums to benefit the open-content movement.
Wikimedia Argentina is the same group that's working hard to organize Wikimania 2009, so they're a busy little group. I'm looking forward to seeing what kinds of events and activities they organize in the future.
