Land is not cheap, and location is everything. I suspect that land you buy will probably be secondary to your primary residence. Land that is close by will be better utilized and more convenient than land that you have to travel a long ways to hunt, and rising fuel costs are not good.
Avoid buying land in areas with a lot of adjacent neighbors, especially ones that like to hunt.... Poaching and adjacent dogs will an endless problem in the wrong area...
The best case scenario, would be a private tract of accessible land that is bordered on several sides by a large "no hunting zone", like a national or state park. At a minimum, you would hope for an area with a large area of natural habitat suitable to the species you like to hunt, even better if that game species is protected somehow. A more likely scenario would be a WL refuge, a state or national forest, or BLM land, (you get the picture) - this opens up more land that is available for hunting, and you could establish a camp, shack, temporary residence on the private piece... Of course this can back-fire, and increase hutngin pressure on your property if not careful...
the possibilities are endless, and larger acreages generally can be purchased for lower prices per acre, though the price tag is often un-affordable. real estate prices are a bit suppressed in this area, so if you have the money, it's a buyer's market now. I wil describe the ideal property:
It's a minimum of 640 acres, holds a high degree of merchantable timber, contains a water source such a creek, stream, pond, or river, has several agricultural fields on it that can be leased to a neighboring farmer, and it borders a much larger area of natural habitat that is either closed to hunting, or has severaly limited hunting for whatever reason... The price is less than $1000/ acre, and once a timber thinning took place 1/3 to 1/2 of the investment was returned. The farmer leases the land with a agricultural crop of some sort that attracts WL from neighboring properties, and the revenue pays the perpetual property taxes on the place. An old 3 room farm house exists on the place, with windows overlooking the fields, woods, and stream, and gives a retreat of some sort to stay during hunting season... Of course, there are huge fish in the lake outside too.
