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.
Citizens Bank Park - 2 hours. The left field gate in Ashburn Alley opens 2 hours prior to all games. As for all other gates, they open 1Â½ hours before game time on Monday through Friday, then 2 hours beforehand on Saturday and Sunday.
