Summer is truly upon us. Three digit days are to be expected in the Central Valley and many of us are relying on time-tested measures to get us through the heat of the day. Some people are lucky enough to have air conditioning or a backyard pool. I live in an old house--air conditioning was unheard of in 1910. We also gave up the pool when we moved into town. So I have to rely on my ceiling fans and iced tea.
