The only time ours went off was when we were camping in Las Vegas..it was on a counter near Kevin's head..he was sleeping on the couch. The windows were open in the trailer so it turns out it was the L.V. air! thus was at 3 A.M. When we all got up and turned on the TV, they were asking people not to drive..we could see the air..looked like L.A.
May I always be the person my dog thinks I am.
Walk towards the Sunshine and the Shadows will fall behind you!
