Ken asked: <snip> I have a business trip to Portland, OR this week with Sunday free. Any interesting on-topic (or off-topic!!) bike stuff to see, like classic-friendly or touring-friendly shops? <end snip>
Ken,
A don't miss shop in Portland is River City Bicycles. They have a great collection of on-topic bikes on display and a nice espresso bar, too! If you're into track iron, Bike Central seems like the specialist in the area.
