For three years, town officials, the business community and many residents in this town in the Berkshires have been split over the role of government in promoting tourism, the Berkshire Eagle reported. Voters will decide on May 2 whether to spend another $55,000 on event-planning and marketing. Selectmen scaled that down from an initial $97,500. Since 2010, voters have approved more than $190,000 for economic development, which has helped expand Lenox’s ‘‘tourist tax’’ revenue, holding down real estate tax increases. Critics say economic development is up to the local Chamber of Commerce, not Town Hall.
