All my life I have chased rainbows. The faster I run, the quicker they fade into the distance. But finally, after 38 years, searching 20 countries on 5 continents, and with the help of my husband, we finally found it. Deep in the Austrian Alps, at the base of an enormous waterfall a double rainbow ends. There was slight danger, much joy, a healthy heaping of luck, great fun, and most importantly, treasure.
