This is not a Concours d'Elegance - it is a shine-n-show (capitalization or lack thereof intentional)... that is, it is open to any car. Hundreds of them. They block off 20-25 blocks of Greenwood Avenue in Seattle, and the cars park diagonally all along that entire route, on both sides. The crowds are huge.
Because of the number of entrants, just getting the cars into place is an exercise in logistics. We had to be in line to enter at 05:30... just imagine how awake we were.
We had attended the show before, but being a participant is an entirely different experience. There is a camaraderie amongst the participants, regardless of their car types (next to us were a 1967 Mustang and a 1988 Monte Carlo; across from us was a funny car dragster) that is invisible to those walking the route not as participants. It was a lot of fun... and a LOT of walking (well sure we walked the route too... much of it before the crowds arrived). In fact, one of the benefits of being a participant is that we got to see most of the cars drive in. That is, we got to hear the cars drive in... Lotta cool engines...
Finally, Jane calls her Mustang "My Little Pony", so of course she went thru the closet full of our children's old toys and pulled them out for placement on the dashboard. They were still a real attraction for girls of all ages as they walked by.
