My grandparent's on both sides had them, one near Overton and the other where Omen lake went in on Mud Creek. They worked ok, but probably not as well as in dryer cooler climates. Still, they overwintered taters, cabbage, sweet taters, root veggies, and kept green tomatoes a long time. They also kept apples. Just be sure to build it with a good adjustable vent and monitor the temp and the humidity.
