Nitrox my friend i've been hunting since the age of 12 and over a period of 45 years my score is not that impressive as that of some of my friends.There are some real hardcore hunters around here who have nothing else to do except hunt all year round.They don't have to earn a living as i or you do as they are all filthy rich and have money to burn.
There are guys who have hunted the Himalayan Ibex and MarcoPolo many times and have hunted Africa over and over taking the big five at least twice or thrice.This year a couple of them are hunting the Central Asian States dishing out $35,000 for each animal(marco polo).
