When we got up the next morning, there was still snow on the ground. I wasn't sure if we would be able to drive out that morning, but I didn't want to wait for the snow to melt because another winter storm was supposed to move in later that day a few miles down the road. I walked along the road within the park a little bit and saw that there was plenty of gravel on the snow to add traction, and heard from a park employee that the highway out of the park was usually kept pretty clear. So, we decided to leave, figuring that if the roads were really bad, we could turn around. The roads out of the park had a lot of snow, but it was a lot safer to drive on than it was the night before. Once we got out of the park, the roads didn't have gravel, but the road had been driven on enough to crush the snow. We had to go a little slowly for a while, but after a few miles, while there was still snow on the sides of the road and on the yellow dashed line, it was just wet where everyone had driven, so we could go pretty fast. We made our way back to I-40 and after a while we got to the highway that would take us to Las Vegas by way of Hoover Dam. The highway was very flat and straight for quite a while, but as we got close to Hoover Dam, we drove by a lot of mountains and then down a very windy road to get to the dam itself. Since I'd never been to the dam, I figured we should stop and look around a bit. We walked around a little bit and looked at it. It was kind of neat, but there wasn't a lot to see. We didn't take the tour or go see any of the exhibits because we didn't want to kill that much time. If I want to hear more about the dam later, I figure I can read about it on Wikipedia or watch a Discovery channel show about it. Anyway, after that we were pretty close to Las Vegas and were able to check eat lunch there before checking into our hotel.
