Hello David.
I actually work a lot and I'm out of the country extendedly so I haven't made any of the local events. I have seen other M6s in the Portland area, however.
Make sure you drop me a message when a meet is going to happen -- I'd love to go if I'm available.
I'm often downtown on Friday or Saturday nights if it's not raining. My car is easy to spot because of the AC Schnitzer rims and the "S85 - V10" custom plate.
Hope to see you around!
