I'd love to participate, that weekend is no good for me, though. The following weekend might work. I will be moving back to Seattle May 12, so anytime after Mid-May would be even better.
You Sammamish guys need to get on the new site
http://www.washingtonwake.com. It went fully-live at the beginning of April, though I have not publicized it at all. It is still in its infancy at about 20 members. Lots of good info including forums, weather forecasts, and webcams from different riding spots all-over the state. Can anybody guess where the background for the logo was taken?
