I am not certain... but I think this is Bethesda Ave.

if this is not where the Capital Crescent Trail crosses Bethesda Avenue today... at least this is what it looked like

believe it... or not...

as a child I walked those tracks to and from school
that was not my route everyday
but it was a popular route
with Tony Morgan I would put pennies on the track for the passing trains to flatten
then we would do other similar things... like smashing bottles and whatever else entertains 4th grade boys

Bethesda and Crescent bring up all sorts of randomness
