Taking a Gamble with the Frost Date

There is always a chance that the last frost will be earlier than average.  So you could roll the dice and plant early.  If you win, your plants get a head start and you might be harvesting sooner rather than later.  However, there is also always that chance the the last frost will be later than average.  If you roll the dice and you lose, you might be outside at night putting plastic and blankets and newspapers over your plants (which can damage the plants).  Or worse, you might be spending your time and money all over again replacing dead plants.
