I had been driving 35 plus hours over the span of 7 days and about 1 hour or so from my destination, I suddenly heard a very loud noise, like a shot! Not knowing what just happened, I began to slow down and pull off the interstate. My legs went limp from fright. Once I stopped on the shoulder, I immediately reached for my “conveniently placed” kit (thanks to Joette's tip from a podcast) and grabbed ACONITE 200c. It was a huge help…. I felt more clear headed and calmer as I examined the origin of the sound…. The sunroof had exploded! Thankfully, no one was injured! When there's fright, grab aconite!!
