There is an extensive underground tunnel system that was used to house
speakeasies under the town of Moose Jaw, Saskatchewan.  We visited there
last Fall, and a tour of the tunnels is one of the tourist highlights.  The
tunnels were originally dug by Chinese coolies who had worked on the
railroad and were trying to find hidden living quarters to avoid racial
persecution and deportation.  The tunnels were taken over by the mobs during
Prohibition.  Al Capone is said to have traveled by train to Moose Jaw to
buy Canadian booze for his Chicago operations.
