Nothing, not even a partial road closure and some imposing detour signs, will keep people from the fair. That’s the hope of Martha’s Vineyard Agricultural Society as the 152nd annual Livestock Show and Fair begins today at the West Tisbury fair grounds on Panhandle Road.

World news intruded on President Obama’s Vineyard vacation Wednesday, with briefings for the press and the president on unfolding violence in Egypt. “The United States strongly condemns the use of violence against protesters in Egypt,” principal deputy press secretary Josh Earnest said.

Fried food at Nancy’s to go, eaten at friend Valerie Jarrett’s house in Oak Bluffs. Dinner out alone with the first lady at the Beach Plum in Chilmark. A round of basketball in the middle. These were the benchmarks of President Obama’s vacation (day four) as he plied familiar haunts.

West Tisbury businesses, from a gas station to farm stand vendors, fear that the partial closure of South Road and prominent detour signs spurred by President Obama’s visit will hurt sales during one of the busiest weeks of the year.

President Obama arrived for a nine-day visit on Martha’s Vineyard last Saturday. The first family is staying at a private home off South Road in Chilmark. Because of security concerns, South Road is closed between Meeting House Road and Wooton Bassett Road until August 18.

Spokesmen for the power company NStar told the Martha’s Vineyard Commission Thursday that they believe the commission has no jurisdiction over a project to install new, oversized utility poles around the Island. The poles have raised the hackles of Islanders and public officials who say they are ruinous to roadside aesthetics and out of character for the Vineyard.

Despite rain showers, President Obama spent his second full day of vacation much like the first, with an afternoon on the golf course followed by an evening out with friends.
