This was the second attempt at this route. And, unlike the Marina walk, it was due to a legitimate mistake on my part rather than GPS signal troubles.
The first time, I continued on the western leg of the “A” for a block south too long. Instead of turning right onto 17th Street, I turned onto 18th Street, overlapping the path that would form the top of the “T”. The result was that my first attempt at this route spelled “rASTrO”–the “C” was missing its bottom.
Crisis averted, obviously. Or, I should say, rrisis averted.
