The King Ranch leases their land to private individuals for hunting purposes. You're probably hunting someones 1000+ acre lease on the ranch. I've hunted the King Ranch a couple times on a friends 1000 acre lease, shot a few doe and a lot of quail. While theyre mostly known for Deer, Nilgai and Quail, I'm sure there are plenty of dove to shoot down there. It's is for sure a beautiful place and I'm sure you will have a blast.
