I'm interested in putting together a photo scavenger hunt in San Francisco. I am currently working on geohunt, a tool to find geotagged wikipedia articles that need photographs.~

Here is my collection of resources so far:

• Previous Wikipedia Loves Art events.
• Previous Wikipedia Takes the City events.
• Requested photographs on Commons.
• Mr.Z-man's Geotagged articles needing images tool.
• Wikimedia's Photo Scavenger Hunt directions.
• The best scavenger hunts I have seen came from Wikis Take Manhatten.

Geohunt's source is available on github, with my todo list and some more info.
