Going west on I40 in knoxville. Visibility so so, I could see 4 cars in front then mist. 4 lanes wide and people start hitting brakes and swerving out of the lane I was in. Traffic scrunches up, then I see it. A semi headed right for me! At least thats what everyone thought! It was being towed backwards and with the rain and mist faked us out. Phew! As I got further west i40 east was bunching up ahead and I saw a trooper with lights on sitting by the median. As I got closer I could make out a a cruiser of some sort on its side in the grass. Hope rider(s) ok. Strangely the bike was surrounded with large items, even a pop up canopy still in the blue canvas wrapper. Maybe he was towing a trailer. There are a few dips through there where the interstate is settling/sinking. Watch for that!
