You're welcome :)

I cut it from the explanation as it was getting too long, but the fact is regularly misquoted as Birmingham having "more canals" than Venice. Venice has more individual canals, but Birmingham's canal system has a greater overall length.

There's three (five when counting both canal lanes) movable pontoon bridges over the Suez Canal that are also used for vehicular traffic, see e.g. here: . Perhaps add a note that you exclude these. Great quiz!
