Jeff gets his second no-prize of the day for bringing us news of the Navy's new "artificial reef" program. Among the first "subjects" will be the USS Oriskany, a large Korea/Vietnam era aircraft carrier. They're going to sink it in 220 feet of water, which is pretty darned deep for a recreational dive. However, carriers are pretty damned tall things. If it settles on its keel the top of the superstructure may be appreciably closer.
