2023 last racing day MGP I ended up at Black Hut in the response car/marshalling and the conditions were very changeable to say the least - the great regular crew stationed there telling me the traditional reference point was if we could see the mast on Snaefell and in minutes it was appearing and disappearing from sight with corresponding "further delays" of 30mins etc that crept on throughout the day, on any other day the practice / race session would have been postponed early doors and I don't recall any chat or consideration of anything happening the day after.
