I grew about 250 watermelons last year. Sold some, gave a lot away, ate a lot. I use the dead tendril method. Not the one closest to the melon, bot the closest one after the melon towards the end of the vine. Thump all you want in the field, doesn’t always work. As for picking one in the store, I look for dullness, darker between the green lines if striped, darkest ground spot, and yeah, I thump if someone is looking :@)
