The Maryland-National Capital Park and Planning Commission is sponsoring a walking tour of Upper Marlboro Sept. 24 and Oct. 1.
The town was founded in 1706 and established as the county seat of Prince George's County in 1719. The walks begin with a tour of Darnall's Chance, an 18th-century property at 14800 Gov. Oden Bowie Drive, and continues past other 18th- and 19th-century residences, shops, churches, cemeteries and the courthouse. The cost is $3 for adults, and $2 for seniors and students. Call (301) 952-8010.
The Silver Anniversary Bugeye Ball will be held Sept. 22 at the Calvert Marine Museum in Solomons in honor of the museum's 25th anniversary. The evening includes a reception in the Museum Exhibition Building followed by dinner and dancing in an adjacent tent. Tickets cost $75, and proceeds will be used to fund the museum's orientation videos. Call (410) 326-3983 or (410) 326-2042.
