I live about 20 miles from Corvallis and I grew up there. If you have any questions, I'd be happy to help!
Off the top of my head for eating, we love Local Boyz on the OSU campus. It's a Hawaiin place and you get lots of filling chicken or beef and macaroni and rice. Also... Something in the back of my head says you're vegetarians though. If you are there is Nearly Normals, my friends rave about it and it always wins awards.
How about you tell me what you like and I'll make helpful suggestions
I know there are lots of clubs in Portland, where's Stinkerbell when you need her! We always do family friendly activities in Portland.
The Kennedy school is really a fun evening with dinner, beer and a movie if it's playing. We really enjoy Gustav's for German food. The Melting Pot for fondue fun. It depends what part of Portland you are in.
Ok, I think I'm rambling, I'll give it some thought and figure out what I'm missing.
