The 3rd amusement park on the list is King's Island. I have never heard of this place before so I looked up it's homepage (www.visitkingsisland.com/). It looks like it'd be fun to visit! It's only 69.99 for a seasons pass, not too bad!

#4 goes to Texas! Schlitterbahn (en.wikipedia.org/wiki/schlitterbahn) is a wonderful place to go on a hot, Texas summer day! I've been there once before, and had a great time! I need to go back there again. Don't forget your sunscreen! :)
Last, but certainly not least... LegoLand (california.legoland.com/) in California, landed the # 10 spot on this list. This place looks liked it would be so much fun to visit! I definitely want to go here someday!
