It’s complete nonsense on several levels. Why leave it a day before the meeting before digging up the track.
the trench only needs to be wide enough for a wire. Spade width at most. No problem for a tractor with its big wheels.
if the trench is wider cover it with plywood to enable the tractor to travel over.
The truth is they completely overwatered the track far too late. Just say it as it is. Apologise to the last few fans you still have.
You can see why no riders wanted to return from last year.
