With regards to people buying land and then making it off limits to hunting, it seems as though hunters rarely look at oil companies as a major source of trouble. In Colorado we continuously have "land grabs" where large tracts of national forests and other public lands get sold at auction only to oil companies. That land will never be hunted on by you or me again. The Three Forks ranch in New Mexico, I believe, is a prime example of that. It is a huge chunk of once public land, bought by Exxon and now hunted only buy oil executives.
