In August I was trying to take some pictures near the Chain Bridge, which crosses the Potomac from Arlington to D.C.  It’s a fairly standard steel girder bridge, but a much earlier bridge at the same spot was a chain suspension bridge, and the name apparently stuck.  I spotted this iron ring embedded in the rock near the western abutment; perhaps it was a part of the old suspension bridge.

Taken with my Sputnik on Provia 100.
