We took a ride to Mount Washington to see the city at night.
It's really beautiful and that's the best place to see it. If you're coming to Pittsburgh from the south or east, you get to go through a tunnel that ends in another great view of the city. Watch for it when you exit the tunnels cuz it's a great view and you're going fast so it's easy to miss. We went through the tunnel to get out of the city and then came right back for the view.
This, by the way is an alternate method of wearing a helmet.
Common in Paraguay where helmets are legally required, he wanted me to assure you that he never wears it that way. Another method is to shove your arm through the head hole and back out the face hole - an elbow helmet.
