Just noticed this thread because you floated it up to the top again CW, and I couldn't help but notice this from an entry on page 1:

I remember reading a hint decades ago that claimed to help with both ripening 'lopes and also preventing rot from sitting on the ground. You put each one on a a pedestal!
Actually, you use a metal coffee can - which, these days, is a rarity. I would think any wide-based can would work. When the melon is about fist-sized, bury the can open end down and balance the melon on the flat surface above ground. The can magnifies the warmth the melon gets so it grows/ripens a bit quicker. If you can find the melons with the shortest growing time you might be able to pull this off? Good luck, if you try it. I never did.
