I don't know anything about Eglin's mission, so I won't comment on that.
FL panhandle is NOT the only place with white sands. Gulf Shores, AL has sugary white sands as well as oil rigs. Its not so apparent at the moment, not because of any oil drilling, but because of not-so-picky dredging practices. We didn't dredge only the purests sands back to the beach, like Destin did. We just sucked up whatever was directly offshore, which happened to be quite a bit dirtier than our normal white sands. The sands are naturally coming back to their normal conditions however. Destin's sands would look far less pure if they dredged sand directly off their coasts like coastal AL has done. A few more years(with a lack of needing to dredge again) and the sands here in Gulf Shores will be sugary white again.
Bringing up the rigs off AL, MS, LA, and TX has nothing to do with "everybody else has XXXX". It has to do with, the rigs at those locations having brought in a tremendous amount of marine ecosystems, just like any other artificial reef, in addition to jobs and more domestic oil. The existing Gulf rigs are mentioned because they show first hand how they can create ecosystems. They set a precedence, its wise not to ignore whats been learned.
Canada, Venezuela, Middle-East, whoever; whats it matter if we don't have to import from them. Providing for ourselves seems to be a much better alternative than importing oil from any other country, middle-east or not.
