Although my 'condition' kicked in on my return -- I ran, walked and waded knee deep over the 5 km course of my current running route. Clear waters. Low tide just at the change. The cohort of the dogs and I had a great time on the sea shore. Today's low tide was extremely low -- 0.3 metres -- so by the time we'd traversed the sand flats and headed due east seaward we met the tide maybe all of a kilometre from the shoreline.
From where I stood looking out to sea I could see more shoals further out at places I had not seen such shallowness before. Deception Bay deserves its name as shoals are notorious deceivers.
This was indeed a low Low Tide.
