If you have the finances, health, and desire, just do it. I wish I had gone when I could have.

Another "agree" here.
I did it when I was younger, and could barely squeeze the finances out....and now that Im in my mid-60s words cannot express how glad I am that I did it!
I'd forego it today just because of the hassles of airline travel... but for those of you motivated enough, I promise not would be worth putting up with the hassles, theres nothing like Africa!
