Report 35593: Possible nighttime sighting by motorists along border of Orland Grove Forest Preserve

My 17 year old and I were coming home from my best friend's house in Lockport, IL,151st to Wolf Road, to 143rd we were driving east on 143rd going to La Grange Road, at 12:20 am on the left hand side of the road, along side the road from the forest preserve was this 7-8 ft all black ape-like creature standing there, I slowed down but didn't come to a stop, I couldn't believe what my son and I saw, my son told me to turn around which I did, we headed back and saw nothing it must have headed back in the woods, my son and I both saw, broad shoulders, long arms it was huge, almost tempted to get out of car and look but we both said no and went home, I did call the Orland Park police dept next day to report and operator said that's a new one on him he never had a call on that before, all I know what we saw wasn't human.
