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.
The stadium in Anaheim has eight gates any fan can use. Seven of them always open 90 minutes prior to the scheduled game time. The home plate gate opens two hours prior to night games. For day games, the home plate entrance opens 90 minutes before the game, just like all of the stadium's other gates.
