Here is a map of Wayne Township:

County Farm and Gary can both be seen on the above map. Driving eastbound on Lies from Fair Oaks, County Farm intersects with Lies before Gary. Kuhn also intersects with Lies before Gary.
One thing I don't recall being mentioned in MSM is whether or not impressions from LS'S tires matched the impressions taken on St. Charles where Debbie's boot marks indicated she left the road and (presumably) entered a white vehicle.
Iirc, one of the many articles linked indicated the tire impressions taken from where she was found on Lies matched the tire impressions found on St. Charles. (or am I confusing the boot marks matching from the swings to the spot they ended on St. Charles?)
I don't think we know what time LS joined the search.
Wayne township goes pretty far west. IDK how quickly one could get from Fair Oaks to the western border of Wayne township back in 1966.
Thank you Cubby for posting the map above. A township is 6 square miles, so quite a few roads could have been traveled between the time Debbie was abducted, and the time she was left along Lies Rd. I don't recall if tire impressions were taken along St. Charles to compare with any impressions taken along Lies(?). Conditions would have been "ideal" (e.g. roads were soft, no frost); although, I don't know the ideal conditions for taking tire casts. If I recall, fibers on the bottom of Debbie's boots were compared to fibers in LS's car, since LS claimed that MAS wore boots that were similar to Debbie's. Another ridiculous "claim" - CYA!! Debbie was 10, MAS was 29 - not even close in terms of boot size. Unfortunately, "forensics" back in the 60's doesn't even compare to 21st century Forensics.
