About 1 mile north of the intersection of 28 and 66, there is a light on 28 specifically for turning into the Park.
NOTE: the athletic fields are WEST of 28. There is a Park entrance going EAST to the south of the athletic fields - closer to 66. DO NOT use this entrance, use the WESTBOUND entrance a mile north of 66 on 28.
From the Hyatt Fair Lakes, get on 286 (FFx County Parkway) south to 66 WEST, to 28 north and follow the directions above.
