I looked on Google Maps to see where that is and it's nowhere near the big dune where everybody needs to be rescued.
The Dune Trail is nearly 3 miles north of the big dune and then you would have to navigate a maze of crisscrossing faint trails to get back to Pierce Stocking Drive. I wouldn't expect the average touron from Chicago, Detroit, or Ohio to be able to do that.
The only other reasonable alternative would be walking south to the forest roads near North Bar Lake, and then finding your way to Pierce Stocking Drive from there. That's still a fair ways away which you can see in the image I attached.
