TUESDAY AUGUST 5 Arrival in Edmonton. As soon as you enter the city, you can see that the Canadian Dollar is king.  Buildings, cars, stores, everything is on a huge scale. Edmonton's prosperity is linked to the petroleum industry.  The surrounding countryside is populated with oil derricks, pumping the precious black liquid out of the ground. However, even that sight didn't prepare us for another breathtaking example of the scale of things in Canada: the first, of course, was the sight of Niagara Falls, but this time it is an accomplishment that exceeds anything one can image: the West Edmonton Mall. The largest shopping mall in the world: a surface area of 40 hectares, enclosed, and air conditioned.  800 luxury stores, 4 hotels, 70 restaurants, a wave pool more than 100 metres long, Fantasyland with a dolphin show, submarine rides, a roller coaster, an amusement park, an olympic skating rink, kilometres of marble walkways, brass, stainless steel, computer controlled fountains, trees 10 metres high, 12 movie theaters, a zoo, etc. etc., all under enormous glass and aluminum domes that make us think about science fiction cities, on some planet far away. More than 100,000 people per day visit this unique complex, and even our friends from California, who certainly are used to such things, were speechless. One of the most amazing things is that, in this party atmosphere, with people going everywhere, and eating, there was not a single paper on the ground, not a sign of anything being run-down.  This was pretty amazing to our group of "Latins".  In fact, this remarkable cleanliness was noted throughout our trip.  Even along the roadside, there are signs warning you about the possible fines for throwing trash out your car window. It's actually a philosophy that we got used to very quickly, and Paris seemed pretty dirty when we got back! Usually, it takes three days to visit the West Edmonton Mall, but the Raid was carrying on, and despite being a little disappointed not to have seen everything, we continue to a campground about 40 km west of Edmonton. That evening, we were even more careful  than usual when zipping up our tents, because the campground manager told us that the yapping we could hear in the woods was a pack of wolves! Good night, Little Red Riding Hood !...
