Sier Safaris, i.e. Luis Sier, is rock solid. Differing from so may others he owns much of the land himself, as opposed to leasing the hunting rights. He has several lodges, and importantly, no trip from the lodge to the shooting fields, that I have ever experienced, is over 10 minutes. You return to the lodge after the morning shoot, and you can nap or whatever until the afternoon shoot.
We were supposed to go early this month, but could not get the required number (11) of shooters to secure the deal we negotiated. We could only get six. So, no dice.
I can't imagine shooting with anybody else in Argentina.
