I found this little factoid about the city i live in- It is home to the steepest street in the United States.
Canton Avenue in Pittsburgh's Beechview neighborhood boasts a 37% grade. Meaning that for every 100 feet traveled horizontally 37 feet are gained vertically
Here we see the view from the top and here we have the view from the bottom.
Tomorrow I plan on driving over to Beechview and taking a ride up the hill (assuming there's not much snow on the road).
