Today we left Vegas and headed off to the Canyon. On the way we went via the Hoover Dam. It is massive. We walked across part of it. It is so hot here that we do not stay outside for too long. Approx. 40 deg. On the way to the Grand Canyon we get stuck in traffic due to a vehicle fire that traffic was moving at only 4 kilometers per hour. We were in this traffic for nearly two hours. When we got up close a car had gone into the back of a tanker and exploded. There had also been a grass fire and the freeway had been closed in both directions. We finally arrived at Grand Canyon at 7pm at night.
