Just returned from a Tulip Time cruise to Holland and Belgium. Here are some of the things I learned:
There are over 7500 varieties of tulips.
In the early 1600's, Holland experienced "tulipmania," when people invested everything in tulips and later lost everything when the tulip market crashed. (Sounds like 2008, doesn't it?)
In Amsterdam's red light district, women sit in the windows displaying their "wares" but they don't want you to take their pictures.
Near the end of his life, Vincent Van Gogh was painting a picture every day. He only sold one picture during his lifetime.
In Belgium, every other store is a chocolate shop (a no-no if, like me, you get migraines from chocolate.) Everything you can think of made of chocolate is for sale, even chocolate boobs.
Windmills served as living quarters (very crowded ones) for the miller and his family. Most windmills today are powered by turbines.
The Belgian Atomium in Brussels, built for the 1958 World Expo, is an enormous structure with huge globes. Schools sometimes reserve a globe and the children can spend the night there.
Bicycles have the right-of-way in Holland and if you don't pay attention, they'll run you down.
