Take Hwy 25 South through Louisville, toward Jackson. As you approach Jackson you'll pass MS-471 N and, after ~8 miles, MS-471 S (Brandon exit). A couple of miles after the Brandon exit, get into the left-hand lane. There is a school zone sign (it is the second school zone) and a stoplight at the high school. Make a left-hand turn into the school driveway at the light.
Games are played in the football stadium (with good bleacher seating) near the back parking lot.
If you reach a set of lights with gas stations and a mini-mall on the right (Grant's Ferry Rd.), you've gone too far.
