Dog Park Meetup....?

It would be fun to have a "DogSocial.com" meet-up at a local dog park in the Seattle area... I was thinking Marymoor Park on Saturdays or Sundays around noon.... If anyone has any other parks, days, and/or times in mind... lets figure out what works best for everyone and their four legged companions.... Of course we could always have more than one meet-up as well...
