I think the visit to Ground Zero (where 9/11 happened) is definitely worth the trip. I went to New York City with my parents and we were just getting ready to leave when I suggested that we go to the place the terrorist attack happened many years ago. So, we went there before we caught our train and we looked over all of the people that were lost and all of the firefighters whose lives had been taken while trying to rescue other people. I found this very sad and I felt especially sad for the families that still lurk this earth. I’m not saying that this an eerie trip, but I am saying that you should respect it and definitely go there :)
