I agree with 30HART 100%. I have done a dozen guided hunts in my life from black bear and whitetails to Dall sheep and Mountain goat. None were cheap for a blue collar worker like myself but I have never come home with an unfilled tag and have a room full of trophies to prove it. Not once have I regreted the money I spent.
My advice would be, if you can scrape up enough cash, go with a proven guide and remove a large obstacle from a once in a lifetime hunt.
Whatever you decide, I wish you luck....
