 The original meet was permitted to be 80 days, expanded to 100 days in the early 1960s.After the purchase by Joseph Linsey, the track petitioned for additional dates, and was essentially permitted to run year-round, with several days per week offering matinee performances as well as evening racing.At the time, nearby Suffolk Downs, a thoroughbred (and later also a harness racing venue) track closed shortly after the beginning of the Wonderland meet, daytime thoroughbred racing in the area transferred about 30 miles away to Rockingham Park, in Salem, New Hampshire, Suffolk Downs generally resuming thoroughbred racing in early September.
