I made it to Salt Lake City. It took me about 12 hours to cover 684 miles. I left at 5:22am and had no traffic or construction problems until I got to just north of St. George, UT when I was stopped by an accident. They had to move three lanes of traffic into one to get by a really nasty looking two-car accident. That delayed us about 20-30 minutes. Other than that it was smooth sailing. Only rain was some fast moving squalls between St. George and Provo.
I met up with college buddy and we leave for Butte, MT in the morning.
