I think you hit the nail on the head. Cool temps and high humidity (raining) seems to be the main problem. It will fog when cold but clears up after a few minutes. Revlis taking your advice you live in the conditions I’m having the most trouble with. Fog City here I come! Thanks Bro.Never, EVER had a real fog Problem until I moved up here. The combination of low ambiant and high humidity combined with a beard and I was having lots of fog troubles.
