Whilst preparing for "CanAK III, Return to the North," I found a niffty way to pack spare turn sig and tail light bulbs: 35mm film canisters (I still have a bunch left over from pre-digital days.) The bulbs fit snugly, glass down and the lid puts just enough pressure on to keep them from rattling around. Eight days and counting. The preparation is half the fun! Ok, maybe only a third but it is fun.
