Tom,
That's amazing.
The day the latest issue of Nat. Geo. with the Blue Hole cover story arrived,
I read it immediately.
I've been on the out island of Eleuthera several times and they have a blue hole
there that I (only) swam and snorkeled in, so I was hoping that it was one of the
blue holes they explored. It wasn't, but I still enjoyed the article immensely.
Do you have this issue? If not, I will happily send you mine.
Tony
