I vote for the I-70 through Utah as one of my favorite routes. The scenery is breathtaking. The mountains are multi-colored and the road winds around to show changing vistas with every few miles. The gorges and buttes and rivers are incredible.
We’ve just returned from a trip through several states and I keep thinking of this particular stretch of highway. It was so enjoyable!
We visited this great old mining town in Apache Junction AZ as the sun was setting. The hills were ablaze and the town charming. Unfortunately, everything was closed up for the day; so it is definitely a place to revisit. The website is at http://goldfieldghosttown.com/ for more information. The amount of old equipment on display was incredible; I found it all fascinating.
