For more than a generation kids have been told to stay clear of the YMCA. It has a deserved reputation as home to pederasts and freaks.
While in the Navy in the late 60s I got back to San Diego a day before my leave was up. I decided to spend the night at the "Y" and report to my ship the next day.
I took a cab from the airport to the "Y". The cabbie ask if I had ever stayed at the "Y". When I said no he told me to wedge a chair against my room door at night. Good advice. The door knob was turned several times during the night. I headed for the ship a lot earlier than I had planned.
