awww..If only it were that easy, EJ. Obviously, Gorillas ARE kept in places other than Africa...there are a few near you...but WILD areas are a pretty delicate balance, and it would not be easy to assure food supply they are familiar with or safety from various predators...including OTHER men.
   I'm sure those with more knowlege than either of us have thought of about every trick they can....but I'd bet the keepers right over at the St.Louis zoo could give you a good idea of the odds of such a scheme working.
