Growing up in Southwest Washington, my dad always had a great vegetable garden. There was always ample corn, sugar snap peas, tomatoes of various kinds, squash, sun flowers, carrots, asparagus, brussels sprouts and many other kinds of vegetables. But one thing my brothers and I always wanted to grow was a watermelon. We planted the seeds year after year which usually yielded a decent looking plant. Some years there would even be an attempt at the formation of an actual melon. But at best all we ever got was a small melon which would never ripen and usually cracked open and rotted.
I recently moved into a house with some classmates and one of them planted a small vegetable garden in the back yard. One of the things he planted was watermelon. So in the future when I'm trying to come up with one or two positive aspects of living in Southern California I can say that at least you could grow watermelon there. I'll still gladly take the watermelon-poor climate of western Washington over So-Cal any day.
The ESV Study Bible is for size comparison. This is the biggest Bible I've ever owned. The melon measures over 2 feet in length.
