After reading all your responds conclusion is that there are better places in the world to live, but it might be safe if special precautions are kept. Unfortunately my would-be employer can not guarantee 24/7 security and he even said that sometimes I would stay in local hotel for night if there was no free place in secure camp. I should expect some night stops in the south part of Libya in the area of Awbari. He also admitted that I would have to buy food for myself, because there are only dinners included between Mon and Fri. Finally, I have other opportunity in my country so I decided not to go. I would love to experience such an adventure and meet completely new, interesting culture but through all the time safety was the most important consideration. Nevertheless I would like to thank you for advises and wish you merry Christmas and all the best in 2014!
Kind regards,
M
