I was seriously looking into this yesterday... weird.. Oh how I would love to become a back country elk guide, however I couldn't take the 3,000$ a month pay cut

.. google.com and then look up "guide schools" You'll pay about 5g's for a 2 week school and then some people it looks like get job offers from there.. If I were you I'd look into doing the advanced school also. Get all the education you can get, makes you more valuable. Get yourself into good shape and learn about horses and pack mules. Decide what kind of game you want to guide for and learn as much as you can about it.
