8/14/2010 7:00 AM T M M M M YES - a TRACE of rain after the coldest 'summer' I can remember since I was a kid... Us, the proverbial mild weather maniacs of the world, have been walking around wanting to light fires during daylight hours to stay warm with a HI temp of 62* the other day! Even the bunnies have only begun to shed! LOUSY summer for tomatoes, chiles, and anything that needs hot, like most fruits.
