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.
Gates open at the regular time, 10:30 a.m., this Saturday and Sunday. The park also will be open May 14-15 and May 20-21. Kennywood begins seven-day-a-week operations on May 25. Kennywood usually stays open until 10 p.m., but could close earlier or later depending on crowd size and weather conditions. One-day admission prices: $43.99 regular (46-inches and taller); $28.99 junior; $21.99 seniors (55 and older); 2-and-under free.
