My dad is visiting from California for a few days. To keep him entertained, we took a cruise completely around Manhattan. It was actually and for real a three-hour tour, and it was a beautiful day to do it today too. I found out about it through Citysearch (which also, apparently just this minute, launched a redesigned interface), and at first I was a little wary of the overtly tourist-oriented air of the cruise’s operator, Circle Lines. While the guide on the boat was remarkably cheesy, he was also remarkably well-informed, and I found out a lot of things about Manhattan that I had never known before. Next time I find myself in a position of trying to entertain out-of-town guests, I’d happily take this cruise again.
