The message
from Chris Bacon contains these words:

New word on me and my dictionary. Google manages it, though. Been at the
Reader's Digest again?

You've never met caltrops? Where were you during the miners' strike?

They've been around for much longer than that. Biggles used
them (it might have been James Bond if I've misremembered).
They were probably used a thousand years ago.

Indeed they were, the Romans used 'em. I just thought that the miners'
strike was a recent memorable example.
