Good luck! I've never had any luck with the rocks or the blocks. I've even tried digging up the ground and putting the loose minerals down and following the instructions and watering them down. I've yet to see any evidence of deer useage on any of these sites. Same goes for things like C'Mere Deer, Deer Cain, Stump Licker, etc.
