Understanding that the repair may be short-lived and only good enough to get me where I'm going, I always carry glueless patches so I don't have to wait for the glue to dry.
One late January day a couple of years ago, I sat along the Delaware River towpath trail in mid-20's temperature, waiting for glue to get tacky because my ride partner, who flatted, didn't have a spare tube, patch kit, pump, or the knowledge of how to use those items, and my Schrader valve spares would not help, as he had Presta valves.
