I'll give you an example of how a T I would be of help,..a few weeks ago ,I walked 6 or 7 fields on the perimeter of a wood,there's lashings of hares in this woodland,but you need luck on your side to get them in the fields,so I was walking this huge expanse of a field,walk up one length,move over a few yards down again,on the 3rd stretch,I walked 20 yards from the wood moved over ,started the last length of the field ,had only gone 20 paces a hare jumped up only a foot from where I had been,it sat tight till I moved away and made to the woods with dog a good bit behind,..I was well pissed of
