Last Wednesday I went to London, and had to use the Underground. I just love it! For someone that uses all the time could not feel that is amazing. But for someone who doesn’t know too much about the city and don’t know where the things are, its amazing, with just a map of the city and a map of the Underground lines, you can go where you want to. For trying to go to the Big Ben, just need to check which the closest station was and try to take the line that took me there.I used the Subway in NY, but even that it’s takes where you want to, I always get lost getting out of the stations, it’s a mystery form which entrance are you going to go out. It doesn’t specify like the Underground form which exit you can go out.
