Pro tip: Sand in the gears from a beach job changed how I pack my kit

I was down in Florida helping a buddy with his old film shooter that got gritty after a day at the coast. The sand had worked its way into the advance lever and it was grinding bad. Had to take the whole side plate off right there on a picnic table, which was not ideal. All my tiny screwdrivers were in a roll, but I learned to wrap them in wax paper first after that. A soft brush and some isopropyl alcohol got most of it, but one spring was a pain. Now I keep a small airtight box just for when I'm working near sand or dirt. It sounds simple, but that one afternoon saved me from a bigger headache later. Makes you think about all the places our gear ends up needing fixes.
