I couldn't sleep this morning so I was up browsing the Internet, and came across a Web site dedicated to the history of minor league baseball in Nebraska (my home state). On it is an interesting article describing some of the history of Sunday baseball and the "Blue laws" that prohibited it. An excerpt:
Nebraska Minor League Baseball; Sunday BaseballHowever, towards the end of the [1907] season they did schedule and play a game on Sunday in Lincoln. Based on a complaint by Rev. Samuel Zane Batten, both teams, Lincoln and Des Moines were arrested. The Des Moines players were fined $1.00 per player and costs by Judge Risser. Ducky Holmes, manager of Lincoln team and the Lincoln players were fined $5.00 each.
