On Saturday, Oct. 6, everyone is invited to join the fourth annual Justin Coleman Memorial Hike-a-thon. The 10-mile hike begins at the Coleman’s house on 150 South Road in Chilmark. This year, the hike also will be in memory of Alex Cohen, a friend of Justin’s who died in an automobile accident driving from Martha’s Vineyard to Duke University at the age of 19.

Artist Lynn Christoffers is exhibiting photographic work prints from two current book projects — Children on the Vineyard, and Cats on the Vineyard.

The works in progress by Ms. Christoffers, of West Tisbury and New York city, are on show at M. M. Stone Fine Art on State Road in West Tisbury, from Saturday, Sept. 29 through Tuesday, Oct. 30.

The gallery is open every day from 1 to 5 p.m. and by appointment. For details, call 508-693-0396.

The four churches of the United Methodist Cooperative Ministry will hold a joint service at the Edgartown United Methodist Church, the Old Whaling Church, on Main street in Edgartown on Sunday, Sept. 30 at 11 a.m.

Benefit Yard Sale

The girls field hockey and girls lacrosse teams are holding a benefit yard sale, Saturday, Sept. 29, from 10 a.m. to 3 p.m. at the Chilmark Community Center. A wide variety of items will be available.

Both teams are raising monies for uniforms and team travel for the current season. This is a collaborative effort with both girls’ sports sharing all proceeds to support field hockey and lacrosse.

Habitat for Humanity of Martha’s Vineyard will host its second annual hole-in-one and putting tournament at Farm Neck Golf Club, County Road, Oak Bluffs on Sunday, Sept. 30 from 10 a.m. until 2 p.m.

This year the shot will be about 60 yards instead of 168. A cash prize will be offered.

Participants may take as many shots as they like, and as many trips around the putting course as they can handle without frustration. Clubs and balls will be provided for those who do not have their own.

Bone Marrow

Next weekend offers two opportunities for Vineyarders to test their ability to donate bone marrow, in the Save Giovanni’s Friends Bone Marrow Drive.

A simple cheek swab procedure will be performed by Caitlin Raymond International Registry. According to state law, your health insurance must pay the donor fee, and if you don’t have health insurance, it’s free.
