Where are all the cars? We’ve driven hundreds of miles since leaving Las Vegas eight days ago. Yet despite the fact that summer is the busiest time of year for the national parks we’ve visited, the lack of traffic on the roads is astounding. Actually, my use of the word “traffic” here is entirely misleading. Because there is NO traffic, at least not in the “Cross-Bronx-Expressway-is-a-parking-lot-with-bumper-to-bumper-traffic-again-They-should-just-bomb-this-road-into-oblivion” way. We arrived in Moab today and it has the first traffic lights we’ve seen since Las Vegas on July 6. I am not lying.
