Maryland Avenue runs from Kiwassa Road southeast to the junction of Fox Run and Rockland Avenue. It was undeveloped until after World War II. With her husband Maks, a pharmaceutical salesman, Ida Haar rented Balsam Manor at 89 1/2 Riverside Drive. The Haars sublet the Bartok Cabin, which backs up to property on Maryland Avenue, to Bela Bartok for the summer months of 1945. Mrs. Haar accompanied Bartok on walks in the woods behind the cabin.
