If you head south past the Loop on I-45, you will run into the Clear Lake/Kemah area. Unless you are the boat-loving outdoors type, the greatest attraction in this area is Johnson Space Center, Houston's famous home of NASA (National Aeronautics and Space Administration). Tours through various NASA buildings—including the original Mission Control room—and other exhibits provide a full day of activities that are both fun and enlightening. If you happen to prefer the "splashier" side of life, you will undoubtedly love this area for its water sports and boating activities. Both Clear Lake and Galveston Bay offer ample opportunities to get your feet wet. In fact, this area has been labeled "the nation's third coast for boating" and contains one of the largest concentrations of pleasure boats in the country.
