Here is a link to the Johnson Space Center.
Johnson Space Center.
The Johnson Space Center is very interesting for adults and probably most teenagers but,it is very boring for young children. There are, however, things for the younger folks in the main building.You can see the layout of the Center in the link above.
There are a lot of photos in this page, so it will take a bit for your browser to open all of them.I thought about removing some of them, but all of them are interesting.
We stayed in the town of Webster at a Holiday Inn the night of February 27th. which was a Sunday. Then on the morning of the 28th. we went to the Space Center which was only about 5 miles from the motel. In the afternoon after the Space Center we drove back to Georgetown.
