Tonight's Reds game commemorates the 75th anniversary of the first night game in professional baseball, which was played at Crosley Field. The Enquirer's Reds Blog posts the Reds' press release here.
Among the highlights: the Reds mascots will actually race around the bases between the third and fourth innings. (Usually, the race is only a virtual one via graphics on the scoreboard.)
Given that the Pirates are in town, though, the mascots would do well to stay away from the visiting team's dugout.
