I'll be hunting them south of there this season. I do think they get bigger out where the whitetails aren't, Ft. Stockton and west, but, just like whitetails in the hill country, there's a few old boys that'll surprise you just about anywhere.
I hunted on a couple of places north of Sanderson and south of Ft. Stockton in the in the 80's and 90's for one season each. The mule deer back then were not much but there were some pretty good bucks killed in the 90's when I did not hunt there on one of the places north of Sanderson. That ranch produced 150-170 type bucks in great years rainfall wise. On years like this and with the management people are doing these days you could be in for a real good hunt. I know there was a low 190's MD buck killed in northern Val Verde in the past few season. That is rare but shows what can happen when it rains out west and it rained a lot out there this year.
