Just because it is spoken on the radio, doesn't mean that it should be in today's ICAO world.
But totally agree with the last portion of your post and that's what I was trying to get at... kinda left a major part missing out of the previous post.
Be very very careful in what you are getting yourself in for while you are there. Try and organise as much as you can before you get there. I'm not saying that everyone there is out to rip you off or steal your things. But you will stand out. And more likely to have something like that happen to you.
