Yes having fun:

We were discussing today how oyster leases should be marked for maritime
mapping. We think probably a cardinal hazard marker (i.e. a hazard lies to
the N/S/E/W of this marker) rather than the location of the hardware for
growing the oysters.

Of course the places where the oysters grow (sorry I don't know the
technical name for this) are the easiest to see from an aerial photo. This
is normally marked as aquaculture in OSM.

The poles marking the hazard are visible on an aerial photo, but you can't
tell from the photo which ones are hazard markers (and which direction) and
which ones are just poles in the water.

 - Ben.
