It is never a good idea to irritate one?s landlord, irrespective of the amount of rent you pay.
This year has, of course, been exceptionally wet and anyone with ground they cut for silage will be trying to avoid unnecessary ruts and marks on the fields.
This also applies to stubble, as driving on the ground when it?s really wet will compact the soil which can cause problems for the following crop.
The answer is either to lamp from a quad bike or to walk.
Walking is totally silent, so there?s every chance you?ll be able to pick up wary or nervous foxes that you would have otherwise disturbed had you been lamping in a truck.
