Dear Neighbors: The Highland Park Community Council's Kids' Committee will be hosting activities to keep the kids entertained during the jazz concert each Sunday evening during the Reservoir of Jazz. I am looking for volunteers to help out with the week's planned activity. On tap are easy craft projects and an obstacle course.  Volunteers need only commit to one Sunday, although if someone really, really wants to help out all four evenings, your efforts would be most welcome. Please respond by return e-mail or call me at 412-482-2533. Thanks for your consideration and hope to see you in the park. Best, Teri
