Radge, you had quite the same idea as I - I was thinking about it, because I've read a book about Afghan and wanted to do that map, but I realized, that there was a very important Salandge tunnel - or somehow like that. And the Idea was - dig a hole, lay a way through it and fill it with a roof-like object. The only thing is, what will the bombs do with it :\ ...I mean - when they fall through the surface, they won't stop and they'll keep falling down... but that's a minnor thing.
