I am doing a little research project. It is all about finding the sweet, juiciest watermelons. My theory is: If the watermelon has scars, it must be from the bugs (not sure what kind) trying to taste it. The watermelon in the picture had a huge, almost hole-like, scar with little scar lines running along the big one. It was one of the best watermelons we have eaten. Please tell me your secret to finding a good watermelon.
