Perhaps because we were staying across the river in Oregon, but it took us three days to find out about this wonderful place. I think we were the only visitors when we went, and I just don't understand why. I learned more about the area here than anywhere else. The exhibits were well displayed, and there were so many of them! The large items, such as the huge steam engine, were impressive. I think this should be listed with attractions for the Cascade Locks area, but perhaps the fault was mine in using the AAA travelbook for Oregon, and it ignores things in Washington, even if less than two miles away. This is worth the admission, and we got both AAA and Senior discounts! I will honestly admit that I don't know if there are concession snacks as we were there no where near a meal time.
