Thanks, your work and dedication are amazing. Finding information and pictures from 1980 can be hard, let alone 1880. I see you have trouble with Cincinatti, er, Cincinnati, or Cincy too. I live near Hartford, CT and they have a vintage base ball club with 19th century uniforms and rules.

A high school teacher was the great grandson of HOFer Roger Connor who was from nearby Waterbury. These ballparks should be good for high school and college parks. I have been using your Jazz Age parks with edited advertisements. I use local ads in my fictional New England league.
