SOuthern Cali folk cannot handle rain. The lack of rain allows oil to build up on roads and freeways. after the first few drops of rain the roads turn into oil slicked death traps.I started driving in 1976. 1977 was the first year with normal rain after that drought.
Boy did I learn a lesson about the Pacific Storms we get here the first time I drove in one of those! It was very scary and I had been driving for a year and a half by then....
