Barry, have not hunted the ducks down there although a lot of my friends have. They have some weird teal, strange pintails, rosy billed polchards, some kind of tree duck and some others. I think you can kill like 60 a day or some shit. We did 3 full days of doves. 8 if us killed just under 17,000.
My friends that still go every year mix it up with doves, ducks and decoying pidgeons, which is supposed to eally be THE SHIT. You can can also shoot perdese(spell?) but most of the guys don't really like that.
