Let me say this ...
If Stephen says "you must see this LSS," then there should be no debate ... get off you duff and get out and see it before, like the KDH LSS, it is no more.
On the way to Cape Lookout from NJ last week, just one was on my intenary (and that was only because it was next to a Lighthsip). Stephen touted me onto two more, both with words and pictures, and they were well worth the stop.
Collectively, I saw the one in Lewes (maybe a "B") ... the one at Indian River (an "A") and the one at Oregon Inlet (an A+).
Anyone with a love for the lure of these structures would do well to contact this young man before exploring. He will do right by you ... and that's a guarantee.
