Taken from Nickol Knoll in Arlington Heights, IL the evening of 5/27/05. I was out taking photographs in Barrington, IL when I got rained out. The rain cleared a bit and this rainbow came out as I was passing Nickol Knoll lookout off of Dundee Rd. It was a very intense rainbow that went across the whole sky. The picture does not do it full justice. I was able to capture the whole rainbow with a wide angle lens. If you look carefully, you can see a second, faintly visible, concentric rainbow larger than the first.
