I was recently out for a "sunday drive" to the SW of the City. In Cresson, I decided to take County Road 918 back towards town. To my surprise, the skyline is clearly visible from where the road crosses the FWWR tracks just outside of Cresson. The view is even visible on streetview. I measure the distance from this location to Burnett Plaza at about 22 miles. The altitue of this site is 1,046 feet according to freemaptools.com, which is about 400 feet higher than downtown.
What other locations have surprising skyline views?
