I hate to tell you this; but there ain't no crock o'gold at the end of the rainbow. I know, because years ago I managed to get within a few feet of a rainbow touchdown. It was on at the beach at Campbeltown. I didn't think it was possible to get so close. So, apparently did the people who put out the story that there was a crock of gold at the end of the rainbow. Some folks just love sending others on fools' errands; anyone got a tin of elbow grease? Now the science is that because a rainbow is caused by light refraction, they are usually only visible at a distance. But, obviously based on my experience, with the right combination of factors, it is possible to be within a few feet of a rainbow touchdown. There are people out there on the interweb who claim to actually have stood at the bottom of one. In my case I couldn't get closer than about 20 feet or so from the multi-coloured spotlight touchdown. So, either there's a treasure trove of over one hundred square feet under the beach at Campbeltown or there is no crock o'gold at all.
