Rocks are very cool. Some can be cool and some are ordinary rocks. I love rocks, do you? I have lots of cool rocks. Some people go hunt for rocks for a living. The thunder egg is my favorite rock. One of the best places to get thunder eggs  is southern Oregon lots of people go there. Lots of people have many rocks and some people do not have many rocks. In my class, we share rocks with the whole class. It is fun. Crystals are a lot of fun to see.
