Joe and I tried to find the nesting great horned owl at Conowingo but didn't. We then tried to find Kollars Nursery but didn't. We then had a nice dinner at a diner just over the PA line. We want to try for Kollars Nursery again. We were looking for it at 5200 West Heaps Road, Pylesville. We found Heaps Road off of Rt 136 but no luck in finding the nursery. Would appreciate help. Thanks.
