O WHAT can ail thee, knight-at-arms, 

Alone and palely loitering? 

The sedge has wither’d from the lake, 

And no birds sing.

from Keats. La Belle Dame Sans Merci

I have often wondered about that phrase, "sedge has wither’d " - perhaps this is it.

But no, this is Florida. The only armored objects are the alligators, though I suppose the manatees might do for the Belle Dames. A happy thought

I saw their starved lips in the gloam, 

With horrid warning gaped wide, 

Sounds like alligators, so cruelly abandoned by their manatees...
