Here is a nice puzzel?
How would you tag a path that lies under an overhanging cliff?

Conceptually I view 'layer 0' as ground surface .. but in this
location/cross section there are 3 'layer 0's - the top of the cliff,
the path and the 'roof' of
Oooh! I'll bikeshed, err I mean bite!
Is the path underground, so could you use layer=-1? If not, then
layer=0 sounds good to me.
