It is four thirty in the morning and the sprinklers are going. I’m hoping for the best, minimal crop damage. The wind machines woke me just after three. My alarm was set for three thirty but by then I was starting the pump. As soon as the sprinklers came on ice started to form on the metal bridge. The only thermometer I have is the car thermometer and it’s usually accurate: 35 degrees right now. Lee just called and it is 33 degrees at her house and she's going up the hill to the greenhouses to cover the tomatoes. I guess I will go take a look around. It’s cold!! out there and a lot of ice. It is five thirty now and I hope this works because our irrigation system was designed to irrigate not for frost protection.
