Harker Heights is a fairly young city, having been incorporated in 1960. The city has no major industry, which is why most of its residents work in Killeen, Fort Hood, or other areas of Bell County. Harker Heights has four recreation areas as well as the Killeen Municipal Golf Course and Stillhouse Hollow Lake. On average, the warmest month is July, the coolest is January and the maximum average precipitation occurs in May. The population as of 2000 was 17,308.

Killeen, located in the western portion of Bell County, is about 40 miles north of Austin on U.S. Highway 190.

The population of 1,300 in 1949 reached 86,911 in 2000. Like it's neighbors, Killeen also has a temperate climate, and an average annual rainfall of thirty-six inches.
