The Howard County Historical Society will hold its 38th annual Holiday House Tour from 1 p.m. to 6:30 p.m. Sunday, Dec. 14. This year's tour features five historic properties around Elkridge, including Rockburn, the newly renovated Belmont Manor, Maycroft, Elkridge Assembly Rooms and Grace Episcopal Church. Tickets are $40 to $60, and for a $10 donation, a snack pack that includes a sandwich, chips and choice of wine or water is available. Bus boarding begins at 12:45 p.m. at the Howard County Library's Miller branch, 9421 Frederick Road. Buses leave at 1 p.m., so participants should arrive early to park, check in, pick up snack packs and board buses. Wear low-heeled shoes and bring a flashlight for assistance in seeing and walking.
