If the parameter is hitting the magical 200" mark (or even close) than my choice would be Sonora also. Thirty inch mule deer are there and you will see them. I suggest Arrow 5 Outfitters as they are having an amazing season (they are hunting now) and have taken several bucks over 30" this year. I would also suggest adding Coues deer to any Sonora trip - those litte deer are quite the challenge. Check out Arrow 5 @ http://www.arrowfiveoutfitters.com/html/mexico.htm.
