All are invited to a 100th birthday party for Connecticut state parks on Friday at the pavilion of Sherwood Island State Park in Westport. Sherwood Island was the state's first state park, according to Friends of Sherwood Island State Park, which is sponsoring the birthday party picnic.

At the party, from 6 to 10 p.m., there will be a strolling barbershop quartet serenading guests, a 1917 touring car with people dressed in period costumes, appetizers and a menu choice of lobster, prime rib or grilled chicken with all the fixings, including New England clam chowder, Connecticut corn on the cob, salads and celebratory cupcakes. There will also be a silent auction, and a live auction featuring "Breakfast with Senator Richard Blumenthal in the Senate Dining Room," donated by Blumenthal, and a canoe trip for three conducted by naturalist Frank Gallo from the McKinney Wildlife Refuge. The evening's raffle prize are animal prints made by Beardsley Zoo animals. Westport First Selectman Gordon Joseloff will receive this year's True Friend Award at the party. The rain date is Friday, Sept. 20.

Tickets are $1,000 for eight guests, with the opportunity to dine with a Connecticut elected official; $1,000 for a table for 10 guests; and $75 for adults and $8 for children at picnic tables.
