I keep an orange high-lighter pen in my camera bag for marking the route of my trips. That makes it easier to retrace my path later, when I’m captioning my slides.

I carry an 8mm socket wrench, without the handle, to tighten the leg locks on my older Bogen 3021 tripod. When the legs start to slip, I tighten the locking levers with the wrench. Most bicycle shops carry pocket-sized metric wrenches, but all you really need is an 8mm socket found in most hardware store tool departments. Keep it on your key ring.
