Did you go to the council or anything cause i'm in that predicament, don't know the farmers and don't know where to find them.
what you need to do is look out for fields and land with coneys on it sometimes it helps lol look out for people looking after there horses etc walk other and ask them say ecuse me do you own this land and so on sometimes they might say no and then you say do you no the person who owns the land and then get is contact details easy all you got to do is ask nowt wrong with that just be carefull with strangers dont go walking up to a dodgy person. best of luck tourmen
