The event in Redmond, WA, is called Exotics @ Redmond Town Center. It's basically a Cars & Coffee for exotics. They meet every Saturday morning, weather permitting, from 9-11am, officially, but it is best to arrive about 8:30 to get parked well and to see the other cars arrive. Your Lotus will get you in - there's no charge. You'll see some nice cars.
The best way to stay informed on that recurring event is to look for them on Facebook - search for [email protected]
