Report 65867: Daylight sighting along Lake Huron north of Lexington

On August 1st, 2020, my 3 sons and I were out for a day-trip drive along the Lake Huron shoreline, north of Lexington, MI. There's many stretches of wooded areas on the lake side of the road, and rural farmland on the west side, along this route. At approximately 12:50 PM, 1 and a half to 2 miles south of Port Sanilac, MI, we were driving northbound on M-25, and my oldest son (15 yrs), seated next to me in the front, said "Oh my God" and stared straight ahead. I was still driving, and asked him what was wrong. He didn't initially answer and his 13 year old brother (seated behind him in the backseat) also asked him what was the matter. He finally spurted out "I just saw a bigfoot!". I thought he was joking at first, as he's always been a notable skeptic of my interest in Sasquatch research. But he adamantly insisted he wasn't kidding and described what he saw in the woods on the east side (Lakeside) of the road. He said he saw a large dark figure walking south through the woods. He says it was too a dark in the canopy of the woods to see a face, but the reason he noticed it at all was that it was moving exactly like the figure "in that old grainy footage that everyone always talks about" (the Patterson footage). He says the arms were longer than its torso and that he could tell it had fur much in the same way you can tell a dog has fur from a distance, that it wasn't skin that he was seeing. It was definitely walking, not standing still, and it's arms were swinging. He guesses that it was around 100 yards or less away. He estimates that it was around 8 feet tall (he said his impression of it made him feel short. My son is 6' 2"). He says it had very broad shoulders. He was able to watch it for approximately 5 seconds as we traveled in the opposite direction that it was headed. As soon as he told me what he'd seen, I turned around and drove back to the location. Traffic was moderately steady, being a summer Saturday afternoon, so it took a couple minutes to return to the exact spot and then find a safe spot nearby to pull off. We didn't see anything at that point, but I pinned the area on my GPS. The exact coordinates are 43.391164, -82.539186
