Get your tickets now and hop aboard the Montgomery Modern Bus Tour on Oct. 5 to explore various modernist sites in the county. As part of Docomomo’s Tour Day 2013, Montgomery County Planning Department’s Historic Preservation office, in partnership with the American Institute of Architects Potomac Valley Chapter, will host the tour from 10 am to 2 pm. The tour will include, among other stops, visits to two Keyes, Lethbridge & Condon neighborhoods: Potomac Overlook (a house in the neighborhood is pictured above) and Carderock Springs, and a custom home by Marcel Breuer in Bethesda. Participants will also enjoy lunch compliments of KONST at the River Road Unitarian Church, also by Keyes, Lethbridge & Condon, and tour the building as well as the compatible recent addition.
