Oh yeah, I've hit nasty fog in Garret County on more than one occasion. I remember one time I was headed home and around Cumberland one of the "Weather Alert" signs was blinking, so I changed the station to see what was going on. It warned of fog and taking caution. I proceeded on and didn't hit anything for the longest time not seeing anything until it was like a wall of fog. I might have had 3 feet of visibility. Had a similar situation, more than once with snow squalls in that area too.
