No, Florida does not allow people to dive on wrecks and take home momentos.
 However, this does not mean that tourists don't do it, or that charter boat
owners don't allow it to happen.  Florida has generally been pretty good
about trying to enforce its rights to "treasure" to keep it out of the hands
of the treasure hunters.  They lost a round or two with Mel Fisher, but at
least the state got some of it, which is on display in Tallahassee.  Most of
the rest of Fisher's stuff has been parcelled out among his investors, and
heaven knows where it is now.  Some has no doubt been melted down or made
into jewelry.  It is now mostly lost for analysis.  It makes one want to
weep.
