Welcome to AH Yumitori!
I am sure that there are plenty of outfitters that can make your African Safari a dream come true.
I believe that a person is capable of doing anything if he has his mind set on it.
Here is a true story of a man that I admire most that might give you motivation to take that trip...
I hunted with a client in 2006 who has since became a very good friend of mine. Klaus, a pure German born in South Africa, broke his neck diving into a swimming pool at the age of 33. He spend months in the hospital and Dr's said that he will never walk again. Being the hardheaded German that he is, he decided that he is going to prove every one wrong and his long path to walking again began...needles to say he succeeded.
Klaus walks slow and with difficulty but he can walk. He still have a lot of pain from time to time and sees a physiotherapist ever second week.
When he booked for the first time he explained his limitations and we took it from there... ever since me and my avid hunter friend have been hunting together every year and I was fortune enough to share his greatest moments in the African bush with him.
He bought a pair of walking sticks and went to Namibia were he walked out Dune 45 and Dune 7. After that he hunted mountain reedbuck on foot in the rocky hills of the Norther Cape.
Every accomplishment he makes just motivates him more and more for the next challenge. He is now 54 and have plans to climb Mount Kilimanjaro.
So my advice to you is don't let anything stand in your way to fulfill your dreams. If there is a will there is a way and do it sooner than later...
Happy hunting!
Herman
