Join us Saturday for Wikis Take Manhattan: a photo scavenger hunt for free-content images for StreetsWiki and Wikipedia. Prizes include Eye-Fi memory cards, which automatically upload photos from your camera to your computer and to sites like Flickr.

Here’s video from last year’s event.

Tomorrow’s hunt coincides with Open House New York weekend, where you can also catch Livable Streets’ Rebecca Jacobs leading a Times Square walking tour for kids age five and up.

So grab your camera and meet us at The Open Planning Project (148 Lafayette St.) at 1 p.m. tomorrow. We’ll send you out on a wild chase that may just win you a free bike trip to Tuscany.
