Take a 45 minute drive south on route 99 to McMinnville OR and visit the Museum there. The Howard Hughes Spruce Goose and lots of other interesting planes are now in residence.
Some great Yamhill County wineries are located along the road as you head south (two lane road for part of the trip so you might be in traffic) with wonderful Pinot Noirs. I recommend Rex Hill for buying and or tasting myself.
Linfield College is a small, liberal arts college located in town.
