Interesting that they're in Northern California and get Seasonal Affective Disorder. I live at a similar latitude (except in the Southern Hemisphere) and have never considered that it would be a thing outside of essentially polar latitudes. Over the past couple of winters (I moved further south a few years back) I've had some atrocious winters in terms of mental space. Maybe this is something I should look into.
