If you are short on time in Dallas, this trolley tour is a good one to use to learn about the city. It's not your typical hop on hop off tour as in other cities. It's about an hour and a half but there is only 1 trolley running so if you hop off at a stop, it's at least an hour and a half before the trolley is back. Just keep that in mind. Bus driver was awesome and very knowledgeable. I did not get her name unfortunately.
