I am flying out to San Francisco next week for business. I will need a couple of flashlights while I am there (setting up and tearing down product demos in a potentially dark space) and I want to stick a couple medium to full size MagLites in my carry on. I hate checking baggage and would like to avoid it if possible. Flashlights aren't on the TSA's published list, but I would hate to get to airport security and find that they consider long, metal flashlights to be a club. Anyone have experience with this?
