If you are going to visit Pittsburgh, you have to do ride the incline. I think it's a rule. It's a rule Joey, isn't it? Yeah. Joey says it's a rule. Don't make him kill your snowman.
The best time to do it is at night when you can take it up to the top of Mount Washinton and look out over the city from the amazing view.
Just be aware that the incline blazes at a heart stopping speed of 6 miles per hour. Make sure you hold on tight.
