A young couple was planning to move across the country and decided to call a local estate agent to locate a place. When the Agent told them she had a nice home at a very attractive price, the man asked about its location.
"Well, there's good news and bad news," the Agent said. "There's a chemical plant just north of the house, a tyre manufacturing plant just to the south, a sewage treatment plant to the east, and the town rubbish dump just to the west."
"My goodness," the man said. "What could possibly be the good news?"
The Agent replied, "Well, you always know which way the wind is blowing".
