When growing up (in the 40s) on Sacramento St. behind the old Children's Hospital, there were those old heavy streetcars rumbling past our home. Don't know how us kids managed to sleep through the racket they made.
Also remember when there were three different lettered streetcars on Geary. The A, the B and the C. I remember that the C ended at 2nd Ave. and Cornwall.
Also remember riding the streetcar all the way out to Sutro's Bath. The line ended at a wooden car barn about where the parking lot is just below Pt. Lobos.
