We try to air the lighthouse in sunny, breezy days to prevent mold and algae growth. It takes at least an hour to walk there and back. Tim opened it in the morning and I closed it before dinner.

To my delight, I saw several rainbows during my walk.

When I got to the lighthouse, sea squalls looked like clouds rising directly from the ocean.

And there were more rainbows arising from the sea.

Magic.
