Larry Benoit and his three sons from northern Vermont. They have been around for 40+ yrs. They are the absolute best when it comes to tracking deer. They don't need snow, but they are the first to admit, it sure increases their odds. As an example, Lanny, one of the sons has an average dressed weight of over 240 pounds for the last ten yrs. This was in a recent Outdoor Life mag.
