I was just in Washington DC recently, and while looking up spotting information for KIAD, I stumbled upon the Washington Baltimore Spotters group. (www.washbaltspotters.net)
I was thinking it might be a good idea to start something like that here, in Seattle, as I am new to aviation photography, and it would be awesome to go shooting with others. I would be more than happy to set this up, but I wanted to make sure that A. people were interested, and B. there wasn't something already like this. I know there are a lot of Seattle-area spotters, it would be nice to be part of an organized group.
