Visiting Mineral City!

    Mineral City is an interesting place to visit. It is a beautiful little town with many old buildings.

    Take a walk through the center of the town on Main Street. Look first at the Mineral City Hotel. It is on the corner of Main Street and Glenn Avenue. It is about 150 years old and people will stay there. There is an interesting old building across the street from the hotel. This was a post office. Now it is a store for books and videos. There are many places to eat on Main Street. You can get lunch or dinner in one of these places. There is a park between Main Street and Oak Street. You can sit on a bench（长凳）in the park. It is nice and quiet, and you can enjoy the trees and flowers.

    You can also take a walk down Glenn Avenue. Look at the old buildings and interesting little stores on this street.
