"There must be something in the concrete in Laval - this is the second time an overpass has collapsed there this decade."
Or not in it - isn't the Mafia heavily involved in construction in the Montreal area?
Shortcuts to save money, skim off more profit maybe?
(Just speculating....)
Leaving something out would be more likely to contribute to a collapse, I would think.
"And the secret of Cheops' pyramid
is that the contractor did
Cheops out of several million"
Indeed it is. In fact, Montreal (and Quebec as a whole) is infested with the mob. And we're not talking Goodfellas, New York style mob guys - we're talking Sicilians straight from the motherland, bringing in huge shipments of cocaine and heroin.
It's actually a very interesting story, for those interested in orgranized crime. A new book has just come out, called THE 6TH FAMILY, that explains it quite a bit (also, NORTHERN CONNECTION is a pretty good primer on the Montreal-New York-Sicily link).
