There seems to be a bit of disagreement about whose fault the mud is. Apparently the contractors say that they tidied up after themselves and the mess was caused by the farm vehicles. However, before the work on the new path started the farm vehicles could travel along there without such a problem, as their wheels fitted in the stony ruts. The farmer told me the other day that 20 tonnes of stone chippings went into the new path, carted along 1/2 tonne at a time in very wet conditions. So, the contractors may have cleared up but by that time there was probably so much mud spread around that the farm couldn't use the track without redistributing it a bit more.
On a more positive note, there's a new, seagull-proof litter bin by the parking / picnic area between the Halfway Station and St. Tudno's. It might not sound much to get excited about but that area's been crying out for a bin and I hope it reduces the amount of litter scattered around there.
