Season of Mist and Mellow Fruitfulness!

I remember learning this poem ('Ode to Autumn' by John Keats) when I was about ten! It matters not that I only remember the first few lines, I am impressed that I remember that much seeing as I sometimes forget what day it is and only realise when I read the TV guide!

We have had nearly a week of waking up to thick mist, or is that fog? And what's the difference anyway? According to Rob, if you cannot see further than one kilometre, then it's fog. But as I cannot visualise one kilometre then it doesn't help! Anything damp, thick and white is mist!
