Traveling to Oxford

I was able to visit Oxford for a day. One of my friends invited me to an Africa Night Event that was taking place at Oxford University, the school he goes to. I noticed how different Oxford was, reminding me of going to upstate New York. It’s more suburbs. I also noticed how on the bus, you have to tap your cards 2 times, when you enter and before you leave or it’ll keep charging you if you don’t tap it when exiting the bus. This is the same for the London trains and tubes but not for the buses in London.
