Cranberry Gingerale Punch for 50!

If you have one of those old fashioned punch bowls (several gallons in capacity), you will find nothing easier to liven up a party (without alcohol) than making a big bowl of punch for folks to gather 'round.  The punch recipe offered here is one that Marash Girl learned many years ago from the Christmas celebration at the Boston Museum of Fine Arts. (Before they built the new wing, they had a yearly free Christmas Carol fest on the marble staircase, after which the visitors got to sip a cup of this delicious punch).   And so delicious it was, that Marash Girl actually asked for the recipe.  The creator of the punch was surprised:  "Oh, it's so simple!" she said.  So simple that Marash Girl remembers the recipe to this day!   Just fill a large punch bowl with ice cubes, pour a gallon bottle of cranberry juice cocktail over the ice cubes, followed by a 2 litre bottle of gingerale.  We use Polar Gingerale, the only gingerale we can find on the market that does NOT have preservatives, and voila!  That's all there is to it!!!
