If you're driving to Corvallis for the conference and you'll have leftover space in your vehicle, please consider adding your name, email, point of origin (presumably Portland or Eugene airport), number of empty seats, and estimated time of departure to and from Corvallis below.
This will make it easier for financially constrained individuals like myself to score a cheap ride. ;)

Another PDX -> Corvallis late Tuesday evening
I can carry as many as will fit in my Hyundai Accent (or similar). My flight is due to arrive at 9:30pm.
