A single breeding pair can produce about 500 mice in about 5 months under ideal conditions. In the wild, their average life span is only a few months. Baby field mice are blind, deaf and bald at birth but mature within about 3 weeks. Females are sexually mature at 4 to 6 weeks. Along with their natural habitat of the fields, they can be found in human habitation including homes and barns.
Fortunately, the Indians know that many fans enjoy entering the park several hours before first pitch, and are willing to accommodate. For a 7 p.m. game, for example, Progressive Field opens at 4:30 p.m., but be sure to line up at Gate C, as it's the only gate that opens this early.
Fenway Park - 1Â½ hours. Baseball's oldest ballpark opens its gates 90 minutes before every game begins. Globe Life Park - 1Â½ hours (day games) or 2Â½ hours (night games) For night games the home plate gate opens 2Â½ hours prior to the game, while all the other gates open two hours prior to a night game's starting time. For afternoon games the gate opening time is a uniform 1Â½ hours before game time.
