USS Blueback - Fast Attack Submarine in Portland Oregon

Across from the Railroad Heritage Center in Portland is the Oregon Museum of Science and Industry. (OMSI) And the flag "ship" here is a boat, the USS Blueback fast attack Submarine. Over a million people visit OMSI every year and some visit the Blueback (and some the 4449 locomotive). Taking the tour of the submarine requires a level of fitness, cause if you don't fit its a problem. If you get stuck (like I almost did) that a real problem!! The boat is mostly underwater so the entire time you are on the tour. The fit is tight with 20 people. Can't believe the crew was 85!!!!!!!! https://omsi.edu/
