Rigging the Harness

I threaded the red twist-tie straight through the bronze key ring, twisting the coated wire three times around the base of the wooden spool. Every supply cart needs a dependable towline, and this one wasn't going to slip. Bracing my boots against the smooth linoleum, I gave the key ring a sharp yank to test the tension. The spool rolled forward a couple of inches with a satisfying clatter, trailing right behind like a trusty pack mule. With the gear hitched and secure, we've got ourselves a mobile depot ready for longer treks.
