First Freeze of Autumn

Oh boy...I decided not to pick lettuce last night because the outdoor temp. was only supposed to get down to 34F. We usually miss the first frosts and freezes being next to the pond. But, when I looked out the window this morning, I saw frozen white water droplets on the porch table cover. Then, when I stepped outside, I went sliding on the deck! Lettuce is frozen, tomatoes (lots of them) are frozen, tiny zucchini is frozen... Moral of the story: If you think there is a chance of frost, cover your plants and pick your lettuce!
