Columbus Day weekend in October
Patuxent River Appreciation Days (PRAD) is an annual festival, which creates awareness, recognition, and promotion of the economic, social, recreational, cultural and historical impact of the tributaries and environs of the Patuxent River and the basin through which it flows. The festival is held annually on Columbus Day Weekend.
The festival brings together, and reflects the continuing commitment of the community, county and state government agencies, the Calvert Marine Museum, the Patuxent River Naval Air Station, and other historical and environmental groups, which share a desire to preserve the Patuxent River and to celebrate its positive influence on the area’s quality of life, in the past, present, and future.
