Last summer I found an extremely cheap flight ticket to Edinburgh flying in the morning and coming back in the evening, so I decided to make a "day trip" by plane to Scotland. I'm really glad that I did it because Edinburgh turned out to be a very interesting city with its majestic castle, and the one o'clock gun, bam!!!. I also solved a question during that trip that had been on my mind for a while (why Scotland and England are part of the same united kingdom). I also enjoyed walking around the city and climbing to this park where I got the chance to get a nice view of the city. I will definitely come back!
