We had limited time to spend in Pittsburgh on a beautiful Sunday morning so we decided to visit the incline. It was a smart choice because it was a great view and cheap to do.
The reviews say to take exact change, but there was a friendly worker there assisting people with the change machine so it wasn't a big deal if you didn't have exact change. No cards though. Must have cash.
There was an observation deck at the top to take pics at and had two of the quarter viewing thingies to get close up on whatever you wanted to see. Souvenirs available at the top.
