Winter weather emergency

On a bitterly cold winter's morning a husband and wife in the back woods of Minnesota were listening to the radio during breakfast.
They heard the announcer say, "We are going to have 8 to 10 inches of snow today. You must park your car on the even-numbered side of the street, so snow plows can get through conveniently".

So the good wife went out and moved her car as instructed.
A week later while they are eating breakfast again, the radio announcer said, "We are expecting 10 to 12 inches of snow today. You must park your car on the odd-numbered side of the street, so the snow plows can get through." The good wife went out and moved her car again.

The next week they are again having breakfast when the radio
announcer says, "We are expecting 12 to 14 inches of snow today. You must park..." And the power goes off.

The good wife was very upset, and with a worried look on her face she said, "I don't know what to do. Which side of the street do I need to park on so the snow plows can get through?"

With all the love and understanding that men who are married to blondes (and those with grey hair) always exhibit, the husband replied, "Honey, why don't you just leave it in the garage this time."
