This will be a ride from BWI, up to Catonsville, down through Oella and back through the shady Patapsco Park.  We will hit historic Relay, Oella , see the Community College, a streetcar path, trolley path, and the swinging bridge.  It is a climb up to Catonsville, with one leg burner but we will go slowly enough to look around and explore this area.  This isn't a flat ride, but there are plenty of bail out options.  Ice cream in Linthicum Heights Coffee Shop afterwards.   Climbing about 2300 ft.  I am reading up on the history now.  If you want to explore but don't want to drive, this is a good choice.
