Schweikert Stadium, Peru, IL, home of the Prospect League Illinois Valley Pistol Shrimp. At least in 2023, the games were free, which is pretty tremendous.

Third oldest park regularly used for professional baseball, opened in 1915. Home of the Evansville Otters of the Frontier League. Some of League of Their Own was filmed there. I particularly like the crazy dugout steps.

Home of the Altoona Curve (Eastern League-AA). The stadium is in a bowl with parking and streets above it. There's also a defunct amusement park over the right field fence. Interesting park.

Home of the Gary SouthShore RailCats of the American Association. Over the left field fence you can see both the Indiana Toll Road and the South Shore train line that runs between South Bend and Chicago.

Now called Modern Woodmen Park, home of the Midwest League Quad City Swing (now the River Bandits) and tucked between the Mississippi River and the Centennial Bridge.
