Thanks Jason - yes, that was a typo in my original post - I did mean as you put it above.
I currently have a .htaccess file in the www.goodsafariguide.com/africa/ folder which looks like:
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)/$ /africa/index.php?GSG_URL=$1 [L]
In an example where the GSG_URL value = alfajiri, this works:
www.goodsafariguide.com/africa/alfajiri/
But not what I'm trying to get:
www.goodsafariguide.com/alfajiri/
