The number one reason is the inevitable threat of cwd being introduced into the wild herd..
Number two is it should not be called hunting..its killing! These places have a density as high as one deer per acre! They are fed, use to human activity and geneticly altered... it also paints a very bad picture of REAL hunters who put in the time and hard work... fair chase is hunting. There should be a a law passed that these places can't use the word hunting in any of their advertising!.. I wonder why P&C or BC or the safari club do not recognize this bastardized way of taking a so called trophy!
But I'm old school.
