I'm willing to be persuaded, but not by repeated assertion. If you can 
imagine a scenario where a valley inside a spinning, hollow asteroid can 
have a line of sight to an observer elsewhere on the inner surface, but 
not to the central axis, you ought to be able to construct a diagram of 
it, like one would in high school physics or geometry.  It doesn't have 
to be fancy or artistic, just demonstrative. I am also willing to do 
one, if you like.
