Checklists are all very well and good...when you're leaving a campsite. My DH got our little TT out of storage last week in preparation for our first trip of the season. He was so happy to be in it, he sat inside the trailer drinking beer and watching TV in our driveway. Mind you, the trailer TV is 20 inches, and we have a big screen in the house, but whatever.
We have a maple tree with branches that hang low over the driveway. When we were leaving the next day, I was behind the trailer watching him back up, when suddenly CRRAAACK!. Antenna, meet maple tree. Bent but not broken...it worked when we set up the campsite, we'll see how it manages the season.
Indeed, sometimes stuff just happens!
