I'm not sure about the rest of the world, but in the United States, we're experiencing an unusually wet and cold spring. I heard that in Sacramento on Sunday, we broke the old low temperature record by quite a lot--apparently our high was only in the low 50s. We've had rain, hail, lightening, and thunder, and up around Lake Tahoe, they've had snow. This weather should continue another couple days too.
Not all of our spring has been this cold, though. We've had some nice days, and the plants are growing and the flowers are blooming. So that means it's pollen allergy season. And mold allergy season. And change-in-barometric-pressure season. Which means it's also sinus headache season. And I have one. ARGH!
