If you're ever there and want a cheap, easy, and leisurely way to experience the city, I highly suggest renting a canal bike. In many ways, I feel like Amsterdam's canals are the soul of the city, and traveling on them you get to see the city in a lovely new light. Plus, it's less than 10€ per hour/person, and it's really not as big of a cardio workout as it may seem. Although I guess I shouldn't be saying anything about that since the boys did all the peddling.
Hope you're all having the luckiest 11/11/11 possible.
