Exhibits marking the 150th anniversary of the Civil War — and a bean hole bean supper — highlight the opening of the Camden-Rockport Historical Society’s 2011 summer season on Saturday, July 2.

Festivities take place, rain or shine, at the society’s complex off Route 1 at the Camden-Rockport town line.

“The supper starts at 5:30 and lasts ’til the beans are gone,” said society director Marlene Hall in a news release.

Besides beans, the menu includes cooked pulled pork, coleslaw, homemade biscuits, homemade pies, lemonade, iced tea and coffee.

Cost is $10 for adults, $8 for members and those over 60 and $5 for children ages 6 to 12. Youngsters 5 and under are free.

“Join the CRHS at the bean hole bean supper and the meal is free,” Hall said.

Belfast Bay Fiddlers will entertain, and supper-goers will have an opportunity to take guided tours of the Conway Homestead at 6 and 6:30 p.m. Blacksmith John Brimson will be demonstrating. his craft before and during the bean supper.

The Cramer Museum and Conway Homestead open for the season July 2 at 10 a.m. Days and hours of operation this summer are Thursdays, Fridays and Saturdays from 10 a.m. to 4 p.m.

This season’s new exhibit is “Call to Arms.”

“We will begin our salute to the 150th anniversary of the Civil War,” Hall said, and will start with the events of 1861, the year the Confederates fired Fort Sumter.

Vignettes in the Cramer Museum depict four 1861 events:

Jan. 21, 1861 — William Conway jailed for heroic event

July 21, 1861 — Picnic Battle at Manassas, Va.

June 21, 1861 — “Now is the Time” – Maine Men recruited for duty
