I always wonder what people do when they are out walking their dogs at night. Last night, Pasiely and I went on a walk that started at the waning end of twilight, by the time we returned home it was fully dark. We passed one other set of walkers while out and I almost didn't see them until they were right next to us. Not cool, people, not cool.
As an avid runner, I've on occasion run during the night time hours and I have one MAJOR rule about being out at night that I wish more people would use: YOU MUST BE SEEN!!
Driving, I've almost hit bikers who think that the meager reflective lights on their bikers are enough. They are not enough. If you are going to a run, or bike, or dog walk when it might be dark the best thing you can wear is a reflective vest, at a minimum. This will reflect the light from the car headlights or street lights and allow you to be seen much earlier. No one wants to be hurt, or their dog to be hurt, because the driver didn't realize a person was there until it was too late.
When I run, I also wear a head lamp that lets me see where I'm placing my feet. My neighborhood is a mix of sidewalks and roads with wide shoulders (but no sidewalk). There are street lights, but often they don't cast enough light far enough for me to always see debris or holes that I could trip on. One of the races I ran at night, had the use of tail lights as an additional safety precaution. I think it's a great idea to be seen from the back as well as the front. Whatever gives you the advantage to be seen is super important.
On our walk last night, I wore my reflective vest, tail light and clipped a light onto Paisley's collar to allow her to be seen. It's one thing for a driver to realize there's a person walking along the side of the road, another for them to realize its me AND my furbaby. When I got home, I wish I would have also brought my head lamp because entering into my caul-de-sac is very dark dark.
See the difference between the two photos below. The first photo is Paisley wearing her night light with the camera flash. The second photo is Paisley as she would be seen normally. While the light is pretty bright, I think I should probably pick her up a little reflective vest as well.
