If you look on a map. St George is on the Arizona border on interstate I15. If you were to leave Las Vegas. north on I15
you would drive about 80 miles to the Arizona line. Then you would only have about 30 miles to the Utah border.
Very scenic country, just about everywhere.
Nice place, near St George UT.
If you are going to Yosemite , don['t miss going to Glazier point.
The view is incredible.
