We went to the Dayton Dragons baseball game today. It was a mostly sunny day, with temperatures around 90 degrees (F). Our seats were down the first base line, and they were in the shade the entire game (although about 2 rows in front of us there was sun). We did not leave the area of our seats for the approximately 3 hours of the game. We had about a 3-4 minute walk from the car to the park before the game, and a 3-4 minute walk back to the car after the game; there was sun shining on us during part of each of those walks (although we also had shade during those walks, too).
My wife was wearing shorts, and when we got home, she found that the tops of her legs were mildly sunburned (and it was NOT wind burn, as there was very little wind throughout the game).
Has anyone ever heard of someone getting sunburn while sitting in the shade?
I tried looking this up on line, and really didn't find any answers.
