"Tex, does this look like it might be an answer for the circular concrete area you saw that was later covered up?"

I probably should remind you that the concrete circle was on GSJI -- "Great". not "Little" St. James Island...

A cylindrical buried "silo-like" structure is a definite possibility -- because that circle is seventy (70) feet in diameter.

However, in one of the drone vids, they appear to be laying out a pattern on it in a geometrical fashion -- as if it were to become a sundial or "Solstice Circle" -- as we see in the middle of LSJI...

Time will tell...

Wondering if drop 3504 is indicating/confirming that under the tennis court is where a bunker is located. Why label the sign “tennis”?

Also wondering if the game theme will continue to make revelations easier to bear.

Were Anons as unsettled by that graphic photo as we were here?

Noted. Thanks for the correction. Maybe LSJI was getting old and tatty and GSJI was going to be the new 'modern' facility?

The reason I asked was because the circular top of that bunker diagram. It just tripped a switch to another of your photos showing that round concrete pad. Understanding they could dual-purpose it with a sundial or some other symbolic topper with the bunker underneath.

Thanks for all your OHI work and analysis! Keep it up.
