Throughout the 1960s, Mountain Park was one of the most popular entertainment spots in the Pioneer Valley. Teenagers flocked to the park to hear the latest rock and roll acts and take a spin on the big rides. Parents relaxed under the trees in the expansive picnic grove. And little tykes frolicked in Kiddieland. Throughout the years, the park was modified and improved, with colorful art deco styling and brightly lit structures designed by legendary roller coaster builder Edward Leis and Rhode Island craftsman Dominic Spadola. Together they designed no fewer than three different walk-thru fun houses and three different dark rides at the park.
