From August 18 to 21, the grounds of the Agricultural Society Hall in West Tisbury will open for the 155th Annual Agricultural Fair.

For four days the Agricultural Fair lured Islanders and visitors from the beaches and golf courses to West Tisbury for livestock shows, tractor pulls, rides, games and food galore.

The Martha’s Vineyard Agricultural Society’s 154th annual fair began Thursday morning under sunny skies.

With the 154th annual Martha’s Vineyard Agricultural Society Livestock Show and Fair less than a week away, farmers across the Island are preparing goats and alpacas, tomatoes and berries to compete for blue ribbons.

Fair excitement begins with the annual unveiling of the Martha’s Vineyard Agricultural Society Livestock Show and Fair poster.
