My brother and I drove from Salt Lake City, UT to Las Vegas, NV in Sept. 2007. Here are some pictures from the trip. The drive was about 6 hours, straight down I-15. The landscape in both Utah and Nevada is quite amazing especially as you get close to the border with Arizona. You'll see some pics of large red rock formations. Enjoy!
We started at about 6:30 am, heading south on I-15 from Salt Lake City...
