Took the kids and granny for a ride on the canal. In Alkmaar, the bridges are so low, you have to literally lay down on your seat or your head gets knocked off as the boat passes under. It's kind of insane, but really funny to see people panicking a little bit.
Small children cannot always properly appreciate the great metropolises of Europe. Amazing architecture and shops where you can look at or even buy clothing from the 1600s are lost on most kids. Come to think of it: that'd be kind of peculiar if your five-year old was really, really into Baroque footwear. So, when they start biting and foaming at the mouth you know that it's time to move on to frites and the zoo.
