BIG difference in that Argentina hunt and what the OP hunt appears to be.
I bet the outfitters down south didn't have you pick your fallow deer, pay for it, then guarantee you'd be able to take it................100% guarantee as I recall.
But, if a dude, or gal, wants to spend $20K for a set of antlers they like, maybe I don't care if they shoot it or by it from an antler merchant.
I do have this tendency to believe it shouldn't be called a "hunt" though. Leave that language out and I'm ok................mostly.
