The Family Stereo System on the Lawn

I hear all about the new grass mowers that my neighbor, Charles, is putting to good use on his 60-acre lawn. But for those, like Charles's grandfather, who have two or three mobile homes, perhaps a better option is to invest in a stereo system that will belt out 50 watts of power. This is simply because in a sense these stereo systems can last for years, whereas a nice lawn will last for, at best, a few months. Makes sense to me.
