Well, I live in Northern Washington now and the sun here is nothing. In Idaho, I ate SAD and burned all summer long. Here, I ate SAD and barely got peels. Now that I eat this way, I cannot burn at all, even if I push the limits! I just turn brown. But I have not tried a day in Idaho, so I don't know how protective the lack of grains really is yet. But I also feel the sun right away and it does bother my blue eyes. So I wear shades if I'm out for a long time, and the warmth has yet to become a burning. I'm pretty sure mileage varies widely on this topic. Are you a red head?
