The dome on the Wyoming Capital reminds me of Colorado's Capitol . When comparing the two capitals, Colorado's is much bigger. However, from what it looked like, there was an additional building on the north side (back side) that could hold additional offices. It was under construction and didn't look as cool as the capital.
Cheyenne is a much smaller city than Denver with a population of 53,000ish. I was surprised that I was able to park right across the street from the capital. In Denver, one would be parked blocks away and have to walk.
