Quite a treat to have an overnight in Newark, NJ en route to our next destination. From Newark's Penn Station, is was a quick trip on the PATH Train straight to the World Trade Center. The Freedom Tower is well underway in construction, and many of the other buildings are following right behind. The Memorial is only available to those who have passes, something we weren't aware of. But there were extra passes that evening at the Visitor's Center - what a stirring tour of the beautiful grounds that so evoke the memories of that awful day, September 11, 2001.
