What would cause a sulphur/rotten egg smell outside of my house?
Off and on for the last several days I notice that I catch a quick whiff of what smells like rotten egg when I am outside of my house. It is very faint for the most part, but once or twice it has been relatively strong. I swear (though it may be my imagination) that I can just barely smell it in my bathwater, as well.
What could it be?
