On day 98, we visited Hach-Otis Sanctuary State Nature Preserve in Willoughby Hills, maintained by the Audobon Society. We had tried to visit this park earlier in our visits, but since this preserve closes daily at 4pm, we had to make our visit on a non-workday that we could get there earlier. We arrived on this particular day a little after 3pm, so we had to hustle through the trails to make sure to get back to the car and out the gate before 4pm. We were pleasantly surprised to find an awesome overlook that was a steep drop off over the Chagrin River which was brown from run-off from recent rain showers.
