We were in Salt Lake City Utah in March 2011. It was a work day and at 3 pm in the afternoon.. However, notice there is NO ONE on the streets. This is the financial core and there was virtually no retail or residential to be found.
Salt Lake City does have an array of interesting features: art, an historic clock shown above, wide sidewalks, decorative tiles in the sidewalks, historic plaques, signage, lighting. Of course, everything is beautifully clean and notice the planters are encased in granite.
