A trip to Chicago

Last holiday I went to Chicago with some friends. We rent a car here in Madison on Thursday and spent all the weekend there.
It was a really nice time. We went to the Millennium Park to see the famous big Bean, after we walked until the Navy Pier, a such beautiful place. We also went to the famous Willis Tower to visit the skydeck, we spent almost two hours on the line to get to the top but worth it !
On the way back to Madison we stopped at Six Flags and had a lot of fun on their roller coasters.
It was a nice trip !
