Highland Has New Pilotage In Avon, Mass. NEW YORK, April 16.
Harry C. Baker, amusement device engineer and amusement park operator, said Highland Park, Avon, Mass., will open under new management this year. New operating corporation, headed by Mr. Baker and Archie Bolter, Boston, plans to recondition the park considerably before opening day. Mr. Baker, agent for the park when it was operated under ownership of the late Charles Bunker, plans to renovate attractions, including Coaster, Whip, Carrousel, Skooter and Aero Swings. Several additions will be made, character not yet decided upon. Park will again utilize its spring water, location (half hour from Boston) and natural advantages for a big picnic and outing clientele. Free acts will be used, some being of large proportions such as rodeos and thrill shows. Highland Park has about 30 acres situated on modern highways between Boston and Brockton.
The park operated at least until 1921 before closing. The park was purchased in late 1924 by Charles E. Bunker. The planned 1925 reopening has not been confirmed.
