Northern California or the Texas Hill Country. California has some downright bizzare hunting regulations vs Texas which seems to be a bit more realistic.
If I had the money I'd buy the ranch I hunt on in Northern California. It belongs to my aunt, by marriage, who just passed away, so it now belongs to her estate. My uncle has rights to about 540 acres of it now. Long story on how that all works out...suffice to say that there is over two thousand acres of prime blacktail deer, hog, turkey, grouse, dove, rabbit and quail habitat with water and vineyard potential in Mendocino County Ca that for a cool $2 million could be mine. But I work for a municipal government, and contrary to popular belief, I am not going to make $2 million any time soon! The vineyard and winery next door (10,000 acres) is looking at it and if they had the cash it'd be gone just for the water rights. If that happens I'm shopping for new hunting grounds.
Other than that I'd have to say one of the NW states or New Mexico. I'd love to live in big sky elk country.
