Thunderstorm!

My friends Deron and Norm are on their way from Nebraska on their motorcycles. They just called from Sterling. It was a beautiful morning--not a cloud in the sky or the hint of a breeze. How quickly things change. I took this picture a couple of minutes ago. Look how dark it is! That big thundercloud is hanging right over our house. I can hear a ton of thunder, too. And it doesn't look much better out to the east. I hope they don't get drenched on their way into town. Maybe it'll pass over by then.
