Here's a great website if you love Santa Claus! The Canadian post is so close to the North Pole that they are the ones that carry letters to the North Pole.
Write the North Pole address and get a letter back, or, if you'd rather, email Santa.
There's also some nice Santa wallpaper, games, activities. Its a very neat little site that will bring a lot of kids and the people that love them a lot of fun.
