I didn't check out whether it was out and lingering today, but the damage was already done from the previous days.
What is vog? Volcanic smog. Particulates in the air too numerous to list. One of them is sulphur.
Before I knew any better, I visited Volcanoes National Park on the island of Hawaii. They have these sulphur pits - cracks in the earth where the fumes seep out. The closer I got, the harder it was to breathe.
What's the solution to the effects of vog? Use the 2 inhalers. Stay in rooms with a/c. Take allergy medication.
And hope for tradewinds.
