Google Earth has a streetview of Newberry and McNamee. Seems like a real nice 10 mile loop with Sauvie Island as a side tour. I saw a lot of turnouts on Newberry. Both are nicely paved.
WSBOB, let me know when you want to do this ride
Thanks for posting the question, Lynnef. Hadn't really thought through one of these excursions until now. Looks quite reasonable for a summer event.
