ok thanks so much sir Jan, I will try my luck next time on that tunnel, it was a straight tunnel about 20mtrs, then it curves about about 5mtrs before the end so u cant see the end when ur at the entrance using a spotlight.. it was well carved on a mountain side, the side of the tunnel is smooth but its not cemented, it has 2feet water inside near the end even this summer days so disappointing to stay for a long time inside of it.. never mind the scan cant afford those..
