As I write this, Colorado is facing the possibility of a second bomb cyclone in a month. It's typically a historic event, but here in the wild west, we do things big. This winter brought record avalanches; last summer we experienced a drought that contributed to deadly wildfires. We're sure to have flooding soon, as the snowpack melts.
Quite frankly, none of that is the reason I carry a car emergency kit year round.
When you live near the mountains, you learn that anything can happen, at any time, without the warning that comes with a bomb cyclone. When it's 95 and sunny in Denver, snow might be falling--and blowing--at the top of Pikes Peak. At least one vicious hailstorm will break windshields every year. Despite the state's best efforts, rock slides happen, randomly shutting down highways.
Add to that your usual traffic accidents and weather concerns, and Colorado drivers really need to be prepared for anything. So I set it and forget it (except to replace expired products). Here's what I keep on hand.
