C'mon guys. Tagging an entire river at layer=-1 is simply not the way to do things, unless it is a covered river or one that runs underground. What other possible justification is there other than not wanting to do the work of tagging bridges with a layer=1? If you argue it's okay if there aren't any crossing/overlapping objects do you mean on the entire planet?
