texas bowhunters has several reports on the lower teniente
i have only hunted the laguna atascosa for them and it was with archery.
they are a tough critter
the land is brush and all things that like to poke you
i have not been to teniente, but it is probably similar to laguna.
very few trees of size, at least none that would hold a tree stand.
thick thick brush along with open areas of high grass or weeds
fyi, if they bust you or spook, they do not stop running for quite a while.
so you better sneak up on them when they don't see you or sit still and wait for them to move thru
i know that is a master of the obvious statement, but i saw so many dudes just walking aimlessly and then acting surprised when the nilgai busted out of there at 400 yds away.
they have eagle vision, it would seem.
