Something that is really neat!!

I was looking at our passports and realized the kids and I got our first stamp in it!! I guess I was so busy that I hadn't realized that customs in Amsterdam, Netherlands had stamped it!! I can't wait till we get the opportunity to get more. I bet our next one will be the Czech Republic! We are not too far from there, I want to go shopping in Prague! How cool would that be? I know that Germany is known for its crystal, I heard that Prague is known for a certain gem/stone I just don't remember what one.
