I HAVE noticed a difference in taste. I have killed deer in PA, NJ, GA, and NC. PA tends to have really good tasting deer in the area I hunt. The deer feed on corn and alfalfa and this is what I find to make deer taste the best. However, my grandad hunted upstate PA in the mountains where there eat acorns and such and he said he hated eating the meat. This is the same as in NJ deer there isnt too much farming going on so the deer dont get to eat the good stuff. Every deer that I have killed in farmland has tasted great, but the ones in mountainy areas and areas with no crops were not soo good.
