If there is a definite trail there using dig a trench about 3 foot deep and at least that wide cover it with small limbs leaves etc ! It will get there attention trust me . When it comes to poachers and trespassersyou have tomake them a believer sometimes. The landowner i hunt with removed two men from his property that he caught the year before and warned them then not to return well they returned last year and he ******ed them with a double barrel shotgun he called the sheriff as he walked themto the his houseand they were arrested on the spot . Needless to say word has gotten around and no one wants to chance it ! You invest lot's of time and money into your hunting you sometimes got to do whatever it takes to get the word out to stay off private land ! Im not saying kill somebody by any means !
