After each emergency event, I review how we handled it and where we can make improvements. Tire chains for the GMC would have been a welcome asset; the last time I used them on a road vehicle was over 35-years ago. With any luck, at least in our area, the threat of major winter storms for this season should be gone in about 8-weeks (although we have had some freak major snow events in April). With what we currently have on the ground, if there is a quick snowmelt we could jump into some serious floods.
If you are looking to better prepare for the next winter weather event, FEMA has a very good guide HERE. No matter how well equipped, trained, and dedicated the first responders are in your area, you may well find that you are on your own for a period of time that taxes the limits of human endurance. Life is a great adventure.
Stay warm and safe.
