The e-tour took a morning stroll at Patapsco Valley State Park and found the "Swinging Bridge" to be a welcome respite from the hot, humid weather that Maryland has been having lately. The bridge was originally constructed to allow passage for the Orange Grove mill workers to pass between their settlement and the mill. The remnants of their historic workplace can still be inspected by visitors to this cool and shady retreat only minutes from downtown Baltimore. We were thrilled to see bicyclists striving to Be Considerate Of Other Visitors, obeying signage asking two wheeled travelers to walk their bike across the span. It's a long way down to the waters of the Patapsco River, and as you can see, space on the narrow bridge is at a premium.
