severe fog?

the fog warning was under the severe weather heading.....was pretty foggy walking early....didn't see any school busses.....maybe it really is a four day weekend .....never did get any rain yesterday right here.....I guess I could cut the grass out back right now, while it's still just 72 and hazy....the chow mien worked well, tasty stuff and enough left for another day.....well, the mail just came....so I'll look at that and then look at the back lawn, decide what to do....
