Horses....

 If you can, get a look at the saddles on these horses.  They're far different from the ones used in the States - Western or English.  They pil blankets on top of the horse's back, then put the saddle on, then more blankets.  The saddle's fairly lightweight and adjusts in the middle to accommodate the horse 's spine.  I'd hate to ride it without the blankets, though.  More horses, more gaucho outfits in this go around.
