We were up in the area of Salmon, Idaho on Memorial Day weekend. It rained as we left town, and I've never seen so many rainbows in one place in my life -- not even in the Burren in Ireland. As we'd drive along one would vanish and another grow, so close that it seemed you could run up and hug them. And most were brightly vivid and complete. We even drove through one.

I've seen a red rainbow. And a blue one, too, although that was kind of hard to see.
