Just got back from the mall. A silver haired neighbor saw me and "waved". Where I am it's 24 degrees so I am thinking this is an indicator that SLW goes to 24 before I see the next silver haired neighbor. To eliminate doubt, the discover channel says that in San Diego, California which is due South and in the Lower West region (SLW) of the State, they have waves 24 hours a day. There you go wave boys..
