15 years ago or more the Scots Guards pipe band was out here in California and competed at the Pleasanton games. The temperature was at least in the high 90s. . . may even have been 100+. Not unusual for Pleasanton. They ditched the doublets and competed in polo shirts. Royal Stuart kilts to be sure, but polo shirts from the waist up. Being slightly less traditional beats the heck out of being face down on the grass from heat stroke. (IIRC, they won their grade, too.)
