That's what the locals do. I just find myself mentally blocked, like I'm some kind of wussy walking around with a umbrella in the sun like a Japanese Gisha girl lol.. But you are so right. Instead I found my self like some kind of crazy with a wet towel over my head! lol. The sun was probably some f the strongest I ever felt in my life. Makes me think there there's a big fat hole in the ozone or something. Was just incredible.
