Next year, there will be a few Spokane area residents who still refer to the "surprise Father's Day sunburn of 2012."
Granted, it wasn't beach temps -- where the need for sunscreen would have been obvious. And it was cloudy much of the time. But those kinds of days can be deceptive. So the sunburns in question would be of the highly localized variety. You know, back of the neck, ears or knees or whatever.
Where on your body did you once get a surprise sunburn?
