Some of you Seattle guys should consider coming out to the annual Burgers and BMWs meet at the XXX in Issaquah on Saturday June 1st. Last year there were a mere 3 ZHPs - mine and 2 others as best I can recall, and not much better the year before. It's sponsored by the local BMWCCA chapter, but you don't need to be a member to attend the meet.
It's a fun meet - lots of really nice cars, old and new, stock and modified.
