OK noting an often lack of important point sites on the other side of the world to pin our cache to on this side of the world, I have used above tool to find where e.g., their national border crosses our big highway, etc.: intersection of two liner features. Hmm, their coastline crosses our river, etc. The only problem is placing a cache upon a busy or wet linear feature...
(Well as my only cache is under my bed, I have little actual experience (that's why it is under my bed... I don't want to be a Virgin Cacher for life ) And not that kind of "busy or wet linear feature" you are thinking of please.)
