Don't mean to detour the thread ; perhaps someone can eMail me.
Back in the 60's, there were four lit towers near the Bronx shore of the Whitestone Bridge. I remember them as being self-supporting.
And as recently as the late 70s there was a similar array, inland from Sunrise Highway, several miles east of Patchogue.
Lol -- girlfriend and I were looking for that site one day, out in the Pine Barrens, and not getting anywhere near it. One dead-end dirt road after another. We'd get back on SRS Highway or some other secondary road, and there would be the green signs for Bellport, Mastic, etc.
And at one such approaching green sign, she cut off one great line, from the passenger seat.
'Towers,' she said, puckishly, indicating a left turn.
But we still never found them to check what they were.
Anyone know what those two sites may have been?
