Explosive residue is me!
As we were cavorting at Snowbird today the subject of explosive residue came up. The ski patrol uses a lot of dynamite and even artillery shells in their avalanche control efforts. The stuff doesn't just disappear when it explodes, it leaves, well, residue! We frequently ski over and through it. It appears as black snow or granules. I haven't skied and then flown in the era of heightened security but I'm anticipating a ski trip which involves a flight. If they sniff my ski gear they -will- find residue! Do I need a note from the ski patrol or something? SLC's aiport may be versed in dealing with this but what about other airports? Hmmmm.
