Casaba Melons, Cat? If so, wait until the skins start to turn yellow, then gently roll the melons away from the vine--if they are ready, the stem will separate easily. It will be a race, though. If frost threatens, cut them and bring them indoors to soften a little--they won't get any sweeter, but they can get less astringent, and more fragrant. Good luck!
