Watermelon Storage

"Yer not 'spossed to put that thang in the fridge!"
A former co-worker grew up on a watermelon plantation in DeePee Texas (deep east). He informed us that the proper way to store a watermelon before you cut it, is in the cupboard. It is perferred that you eat the whole thing as soon as it is cut, but if not, you can store the rest in the fridge.
Consider yourself informed.
