I have some friends that take part of a few of the classic car rally's/tours here in the US. Each year, I drive over to the Fairmont in San Francisco to see the cars of the California Mille before they start their tour around California. One thing all these tours seem to have in common is a name (Rallye Monte Carlo, Mille, Copperstate 1000, Colorado Grand, Peak to Peak, etc), and a way to identify the cars (meatballs or window stickers). Perhaps this group isn't about that, and that's cool.
That said, I have been thinking about our West Coast gathering for the past few days, and if there's any way some of these concepts could be used. For starters, a name to identify this function. With a few exceptions, one thing I thought was interesting about the route most of us take to get to SLO resembles the famous Amtrak Coast Starlight route from Seattle to LA. Therefore, I simply borrowed that route for a tour name, the Coast Starlight.
The other thing was to come up with either a window decal or a meatball for the side of our cars. Option 1 was inspired by a lot of the poster art / decals from the Mille Miglia; just relating it to our event. Option 2 borrows from the graphics/logos of the railways of yesteryear. Option 3 simplifies it all together.
Feel free to sing praises, fling insults (tell me this is the stupidest thing you've heard), scribble on the PDFs, etc. I won't get butt-hurt.
