Let's put the numbers into context. For Entertainment, the Freedom Center ticket was $20 because I bought my ticket at the museum (it's cheaper to buy online) and because there was a $5 charge for the Rosa Parks Experience. It was a virtual reality experience where you got be Rosa Parks on the day she refused to give up her seat on the bus in 1955. It was cool to experience.
For Transportation, the Greyhound ticket to Cincinnati cost a little over $40 because I waited until the day before to buy the ticket. I walked while I was in Cincinnati and I even walked across the John A. Roebling Bridge into Kentucky and had a great view of the city. I also realized that I'm not a big fan of walking across long and high bridges.
