Volunteers in Bar Harbor are raising money to build a better park. The Park Street Playground Project is an effort under the direction of the Mount Desert Island YMCA. Developers say the current playground is in disrepair and no longer serves the community’s needs. A collection of parents developed a construction plan that includes climbable new structures that reflect the rustic image of the town. The new elements will be installed by volunteers but buying them carries a hefty price tag.You can pledge support for the project this Sunday at the Downtown Lobster Pound. The restaurant is donating a portion of their proceeds to the group’s efforts.They’ll also be raffling off Red Sox tickets, along with other gift certificates. The event runs from 12 to 9 P.M. at 297 Main Street in downtown Bar Harbor.
