Yeah Itchigo, it was 1967 and it was big news at the time.
Since then we've had flurries in the San Fernando Valley basin only a couple of times, and as I've said, it is more common to see hail at this low elevation.
Now there is a thriving recreational ski and snowboard slopes business in the mountains about 3,000 ft. or higher elevation from where we are, at Mt. High, etc., and it is often that we hear of snow along the I5 Golden State Freeway north of Saugus and Valencia, with black ice and many fender benders.
