This thread is four years old but still timely.
Funny that Sunday morning I uncovered the White Hawk then got on the roof to measure the broken skylight above the shower. As I measured, I heard an occasional "tweet tweet". I figured it was just birds in the nearby birdhouse.
When I went in the rig, I hear the "tweet tweet" again, then realize it's the smoke alarm telling me it's dying.
