There are instances that I would have to rely on transportation. Sometimes, I have doctor appointments. Other times, I may have to collect a package. There are also the times that I need to get groceries. All of this relies at least on the public bus system that services Allegheny County. This is unique as I prepay for the service I would use. I have one of their transit cards, and I will load $200 on the card. As the card is used to pay for bus fare, it reduces from the $200 that I placed on it. When my balance drops below $25, I will load it back to the maximum of $200.
