I see what your saying, but you have forgotten to take into account that that deer is only probably 5 1/2-6 years old. When a deer is still in it's nymphyl stages it's only about 2/3 the size of an adult. So when we take that into account we can conclude that the deer's body is at most 3 feet long nose to tail, which when we fuigure up the math, and calculated the earth's rotation like was previously mentioned, we get exactly 4 feet 1 and 3/8 inches. Still an impressive spread by any account, but with another 5-6 years like I said earlier, he will be a monster.
