Unfortunately, I probably just plain won't be able to get out there that night. I don't want to impose on anyone to come all the way back to Portland at 9 pm to pick me up, and taking trimet means I wouldn't get out to your area until around 11:30, and by then things will probably be wrapping up. And either way I'd still have to arrange a ride back to Beaverton after the fact because the last bus out of the Tigard/Tualatin area leaves around 10:30 on Saturday.
Also, I'll be needing to go to work the next morning. :/
I hope you have a good birthday, Patrick!!
