Apparently gas leaks are not that uncommon. My sister comes running up to my room telling me that there are cops, firetrucks, and an ambulance in front of our house. Our neighbors had a gas leak in their house. When we walked outside the rotten egg smell was very strong and was the reason my neighbors are still alive. With out that rotten egg indicator their chances of making it through the night diminishes greatly. I am so glad that was mandatory in home making. This is a scary thing. I was curious about the rotten egg smell and found this pretty interesting.
