Excellent kit. A couple of recommendations:

1. Upgrade the Mini-Mag light to one of newer high power LEDs. I've had unleashed dogs race out to greet me and my GSD at night and the bright light causes them to slow down long enough for me to determine their intentions.

2. Get a traffic cone for your light to aid in visibility. Even if you stay on the sidewalks, drivers turning on to side roads and driveways are a potential hazard.

3. Along the same lines, I see no Hi-Viz materials. If you are walking at night, I would recommend a reflective vest or belt. My dog also wears a reflective collar.

4. Depending on the length of the walk, a bottle of water and a collapsible nylon bowl. Even if you don't carry the water, the bowl can be used with hose bibs you may find along the way.

5. No towel? Even a small one can serve many purposes in case of an injury or an encounter with the unexpected.
