When they say no,go back again a few weeks later and ask again,ive had permission in the past at the 3rd time of asking.Be prepared for some downright miserable,rude and obnoxious replys to your requests.Permission now is more important than it used to be,so id go with that route,the best hunting and results are often found away from such luxury though.
thats bang on like i said i had like 800k acre of permishion i now have about 100 but its all shizzle, i have one bit of good land but has taken me 3 month to convince them to let me on and 4 references as they are townies with hens haha, per
