Summit:
W7O/WV-138
This is an urban park activation about thirty minutes from downtown Portland. No GPS device needed as Google maps provides good driving directions. Though you can pull off a 2M sidelwalk activation near the summit (which is on private property), a more pleasant place to operate from is Skyline Ridge Park (45.3905, -122.6634), about a half mile south. RF noise levels are high, so while a nice spot for an activation, don't expect big things on the HF bands.
