Laura O. Foster shows her favorite out-of-the-way places in Portland, Oregon City, Forest Grove and other intriguing locales. Hidden urban stairs, river cobbles thrown high atop mountain slopes, street trees that began as seeds carried north in a saddle bag from the California gold rush, old streetcar districts recharging with new commercial lives, a convent and orphanage whose architect was not only a woman but a nun. All these small and large elements of our history in plain sight constitute a rich vein for a forensic pedestrian to explore. Tickets: Members $10, General Public $18, available at Organizer link above.
