never had one THAT big
we get anywhere from 1 to 3 dozen a year around my place. if around house, they go to pitviper heaven, if out and about i leave em be.....they help control our vole problems.
my wife will have nothing to do w/ RS cuisine, as such, never tried one. largest one i've seen in over 10 yrs was about 5 1/2 - 6 ft and only 14 buttons, but end of tail appeared broken off. mostly we have babys through 3 footers.
