I used to have a friend that was a rice grower in SE Arkansas near where you have your lake place (he passed away several years ago). He told me that he tried pepper spray around the edges of his fields because the deer were really giving him fits. He said even the cardboard boxes that the spray containers came in had to be handled with gloves this stuff was so concentrated. He said the deer ate the rice that was sprayed with it like candy.
