i sort of breeze over "office stuff" posts because i'm not in one anymore,but something i have not seen just looking at a post or three is ice grippers.the Yak Tracks, rubber with steel coils are easy to slip on and work great.i use them for winter dog walks.a set of those in your kit would make the walk home or to a safe place fast and easy if you have to bail out in winter.which i'm very happy is over for the most part here.
