Don't blink, or you will miss it!
Every few years, the Tour de France comes through Pezenas. The first year, we found a spot along the route and waited a few hours. It was pretty crazy! First they have a Caravan pass through. It is basically sponsor vehicles that have been modified with logos, sculptural details, and occasionally scant ally clad dancers. Kids love the caravan because all of the cars throw samples, shirts, hats...whatever to everyone on the side of the road.
There are hundreds of motorcycles with cameramen, officials, whomever.
Finally the riders come through. Everyone goes crazy yelling and screaming. Again, there are hundreds of riders. They all pass by in seconds, and then it's over. It really is like the circus blew through town.
