Take Hwy 25 South through Louisville, toward Jackson. As you approach Jackson you'll pass Northwest Rankin High School on the left. At the second stoplight past NW Rankin - Grant's Ferry Road - take a right.
Grant's Ferry makes a T junction at Spillway Road. Turn left. The soccerfield entrance is just past "Rapids on the Reservoir" (before you get onto the main spillway).
The fields are back off the road a bit ,and there are fields at the other end of Spillway Road that might confuse people (you can see people playing soccer there).
Bring chairs, there are no bleachers or stands at these fields.
