Last summer I did a little experiment by burying a little plastic trash can in a hinge cut area next to a trophy rock. I was pleasantly surprised that about every critter you could think of used it (trail cam). Back in March I buried a small swimming pool in an area where deer travel and where rain would refill the reservoir for me. I don’t have the first video of anything using it. It kept water in it back during that short but hot drought we had in May. Put 10 pounds of corn around it a couple weeks ago to draw deer in, only to find the corn untouched. Anyone else made a watering hole deer don’t like?
