I have a strange fascination for this idea..  Seems like something that
could be quite fun.  Brings back memories of the days just before I got my
licence and was studying for the CW test.  A friend and I used to exchange
messages in Morse while stopped at traffic lights by flashing our stop
lights.  This kind of brings back memories. :-)

Then there's the other week when another ham spotted me and sent "CQ" in
Morse on the horn.  That had the desired effect, gave him a call on the club
frequency! :)

And who says Morse is boring? LOL
