Stuff 'em, i've got some land that runs alongside a dual carriage way. There's holes all the way along the hedge and on the verge and i've always ferreted these with out any trouble apart from the odd anti driving past pipping sticking his fingers up. On a few occasions when theres no crop in the fields these warrens have been the best ones for holding.
same here mate i have the same on some permission i have got and we do the holes on the road side like you said you get antis beeping and sticking they fingers up at us we just give them it back f**k'em
