It's been very cold the last few days, so seeing as it was low tide at a convenient afternoon hour, I just wandered out to see if I could see the hot well steaming. I've been told that you sometimes can, on a cold day, but today, as with every other day I've tried, there was nothing in evidence.
It may be that the emergent spring has already filtered through too much cold river silt by the time it hits the surface these days, or even that it's running cooler than it used to. But perhaps I've just been unlucky.
