im afraid it happens in most areas ,young lads come into the game try their hand at lamping(glorified ps 2 game ) kill owt that moves ,piss the farmers off to the extent of blocking all the entrances off to their land.
then(bored) they move on to doin a bit of terrier work ,find on the local grapevine where all the local drains /earths are,then proceed to smash/trench ,obliturate them !
im sure this is just a minority,and im sure most lads that are genuinly into feild sports have heard such a tale
ps had some cracking local drains that we had worked succesfully for25 years obliterated
