Once a year during Hastings Rivertown days, the lock and dam and the hydroelectric plant open up for a tour. Heading south to north, one sees the lock built in the 1950's, then across the original lock built in the 1930's that has been disabled, then the hydro dam.
Just over 1600 B-29 Super Force bombers were produced during WWII. Today there are only two that are airworthy. One these planes, named "Doc" which rescued from the desert after years of being used for target practice. https://www.b29doc.com/ This plane flew into St. Paul, specifically Holeman's Field, for public view and rides. The Commemorative Air Force MN Wing http://www.cafmn.org brought a few planes to join in, featuring their B-25 "Miss Mitchell".
