From interestate 57 & 70 where they are running past Effingham, Illinois,
Exit onto IL 32 & IL 33 (both state highways are running together as they cross the interstate) and head west on 32/33
Go about 5 miles, and the highway will split; 32 turns off to the north, 33 continued west; take 32 north.
Go about 7 miles, and you will see the town of Stewardson on your left; continue north about a 1/2 mile beyond the town of Stewardson, to a small (county or township) road with a sign "Mode (6 mi)" to the left (west). Turn left/west on that road and drive approximately 6.5 miles to the camp. Landmarks to know you are close to the camp: you will cross a railroad track, and then (1/2 mile or so) the road curves to the left (SW), then back to the right (W) and in that Westerly curve there is a road that turns off to the left (S). At that intersection you are looking at the campground (looking SW). Turn south on that road, go about 200 feet to the entrance (on your right) to Shelby County Interdenominational Holiness Ass'n "Mode" Camp.
