I am from San Carlos... and have seen maybe 2 bucks in my lifetime over 120s mark... Its due to great management....not many tribal members hunt coues, due to wanting more meat which is mule deer. Those big bucks killed this year had to do with the excellent rainfall we have this past summer... 7inches more than we had last year so horn growth is spectacular... We have an average of 500 hunters hunt on the tribal hunt in October,and at least 100 nonmember coues hunters in a year with only a 30 - 40 percent success which is good... but there is alot of country on the rez(1.8 million acres of coues). Im not a biologist but a guide who hits the field 100 days out of the year... hope this might explain a little
