In April 1977 the Houston Astros introduced their very first mascot, Chester Charge. Chester Charge was a 45-pound costume of a cartoon Texas cavalry soldier on a horse. Chester appeared on the field at the beginning of each home game, during the seventh inning stretch and then ran around the bases at the conclusion of each win. At the blast of a bugle, the scoreboard would light up and the audience would yell, "Charge!" The first Chester Charge was played by Steve Ross who was then an 18-year-old Senior High School student. The creation of Chester Charge and the (incredible for its day) scoreboard graphics were created by Ed Henderson.
