What an amazing trip it is to go through the Canal. You go up 85 feet from the Pacific Ocean side, go through a very long lake, and down 85 feet into the Caribbean. Watching ships along side, in front and in back makes it seem like ships are rising and sinking around you.
I am sure I could talk for an hour about the Canal but you just have to experience it for yourself. You can see the progress they are making on the new locks for the really big ships too. That is due for completion in 2014.
All in all it makes for a very entertaining day.
