When I was 13 my parents let me visit my Grand Parents in Lake Ronkonkoma ,on Long Island. I took the Reading to Philadelphia then got a Trailways Bus to NYC. I remember that the Port Authority Bus terminal was pretty seedy even in the early 60’s. Walked through the Garment District on the way to Penn Station,while not as big Grand Central it was pretty huge. I don’t think I could do that trip now without being mugged several times.
But a trip like that even in the 60's (which, admittedly, was before my time by a few years) for a 13 year old? I'd never allow that, and I almost never say no.
Good outta you that you had the fortitude to make that trip, and a hat tip to your parents for trusting you enough!
"Feral kids" grow up to be our best citizens if they get parenting at home.
