What is at the end of the rainbow?

The answer, I have found, depends on your cultural frame of reference. In the US we suggest that you will find a creepy green man with a pot of gold. In Uganda, I learned today, the rainbow's end points at a white ship (that has a pesky habit of vanishing into Lake Victoria when pursued). Or, to some Ugandans, the rainbow is a message from a higher being that the looming storm will not show its full wrath on the people. Or to the abundant Ugandan Christian masses, it is a symbol of a promise from God. Who knew those technicolor arches held so much lore and symbolism?!?
