Actually no, same O, same O. Nothing has changed, The 1976 paper was
good as gold. Even if a lake were nearby, it wouldn't change the fact
that the sites are alongside the small runnels, so they are still
NEARER the small (no swimming) bodies of water than lakeside. Ever see
anyone dive in 50 cm of water? :-)
