The small whaling museum on the north side is a must stop. Small, but lots to look at and absorb. The rangers who ‘man’ it can be a fount of info. What a great park! And if you park on the road, you should contribute $10 to support the system.
Yes, that is a great museum!
I just drove to our place in North Idaho from the Bay Area. I stopped at the Sherman County Museum in Moro, Oregon. If you like small, local museums, this one is a must-see. It’s by far the best small-town / small-county museum I’ve been to. I got a private tour by the man who created the museum over 40 years ago and worked tirelessly to get it built. He seeded the many collections himself and invited the locals in Sherman County to donate items. He said they have the museum completely full within a couple months.
