I'm kind of thinking I'll do that same kind of thing. I have one drip line above ground and one zone in front with a section above ground that are susceptible to freezing. Will probably drain out the breaker/pipes & manifold and blow out those 2 zones real quick. Then will start it back up after the cold snap and run the system another couple weeks while it's warm. It's kind of a pain, but probably less than manually watering several times.

Might all be fine covering up the outdoor lines and riding it out . . . but the drawbacks if it freezes far outweigh the work to play it safe.
