This original post is old, but anyone can drive in the MPG rally in Lacey, WA. It's about an hour south of Seattle near Olympia. Always the first Saturday in May.

It's a 90 mile loop that includes varied speeds and elevations. If you are even thinking about it, put it on your calendar. It's a fun, easy to navigate drive and you'll meet several other MPG nuts like yourself. The fair and electric car races are very interesting too!
