Last Saturday was Scott Kelby's second annual worldwide photowalk. You can find more information about it
here, but basically it was a gathering of over 32,000 photo nerds in almost 1000 cities worldwide, but limited to 50 folks per walk. I walked with several friends in Stillwater, Minnesota and had a great time. Was even fortunate enough to meet a few of the folks that work on Adobe Lightroom, which is what I use to edit 95% of my photos.
This is a photo of 3 of my good friends as we set out from the meeting point and started walking:
