quater the fields a bit to find them , always pay atention to the leywood side of little hils and rises in each field. hares will use forms out of the wind very often. cover strips, and set aside are also good places, dont ignore them cos there at the field edge.
also elecy pylons , make sure you walk under them through the bramble and long grass, wish i had £1 for evry one i have flushed from under them. also small spinys in the midle of big fields.
had a good few lads out with me over the years that just want to walk the midle of the fields, but i educated them
