SHOULD BE EASY TO FIND OUT WHO THEY ARE... GO BACK AND MOUNT A FAKE LOOKING CAMERA TO A TREE IN THE AREA AND MOUNT A REAL CAMERA HIGH IN THE TREE LINE LOOKING DOWN AT IT USING A CLIMBING TREE STAND. CHECK IT DAILY. YOU WILL FIND OUT WHO IS USING THE AREA REAL QUICK. CAMO IT WELL. LEAVE A NOTE IN THE FAKE CAMERA STATING PLEASE RETURN THE OTHER CAMERAS....THINGS JUST MIGHT WORK OUT.
