A buddy of mine says a farmer he knows has been planting NON roundup ready corn the past few years as he said there is starting to be a higher demand for corn that is not genetically altered. Anyway, he claims every year he rotates it, the deer are hitting these fields WAY more than his roundup ready fields. I guess he firmly believes the deer can tell the difference. Not sure if there is any truth to that or not, but I found it interesting.
