After visiting Yellowstone National Park, we went to Salt Lake City. SLC is an impressive place, a sort of jewel in the desert (I prefer it to Las Vegas). There's a lot to do and see and it has quite a few brew pubs (a true sign of civilization). You can also practice wedding photography outside the LDS Temple.
On the way to SLC we visited the golden spike museum where the west-east and east-west railway lines met.
