Pre-meet with all the Benzes sounds awesome. I'm thinking we could use "the Lid" as our staging ground; it's a nice park near the highway on and off-ramps for the I-90 floating bridge. The grounds could offer a nice back drop for some pics with all our cars lined up, then we could head down to the show together. Directions to the park below:
From I-90 westbound take Island Crest Way (Exit #7).
Continue straight through the stop light on North Mercer Way.
Turn left onto 76th Avenue SE.
Turn right onto SE 24th Street.
Continue up the hill and turn right onto West Mercer Way.
The parking lot will be on the left just past the I-90 entrance.
From I-90 eastbound take West Mercer Way (Exit #6).
Turn left onto West Mercer Way.
The parking lot is on your left just past the I-90 entrance.
We can worry about setting a time later. Also, make sure to register your ride in the show using the link to the car show. This should be fun.
