Hi all,
Thought I should give a quick update.
On the re-tensioning, I was unsuccessful this weekend. The limitation of the ratchets I bought is the wire has to pass through the middle of the ratchet. If my wire was broken or if I was at the end of a strand that wouldn't have been a problem. Unfortunately, I'm trying to tighten in the middle of a run and I couldn't bend/crimp the wire enough to get part of it through. I thought briefly about cutting the sire and feeding the ends through but decided against that as really making a mess if it didn't work and as the neighbor was standing there starting a conversation. I'll get some of the Jake's Heavy Duty clips and try those. I also plan to study the Gripple products that were recommended. I appreciate all the suggestions and will find something that works relatively easy. I'll let you know how it works out.
Regarding the neighbor, the husband (who I hadn't yet met) approached and started a conversation. While he didn't specifically mention the stretched wire, my take is he was truly embarrassed by the situation and wants to be a good neighbor. I was trying to figure some way to make the ratchet work and finally commented that I would find something else. He didn't say anything but stood there looking down. As I said, I felt he was embarrassed and didn't see any point in hammering him on it. I also think he didn't have a clue how to tighten it. (However, he was very concerned that some of their spent fireworks/wrappers/etc may have blown into my field in the heavy wind that had just passed through.) My read on it is his wife mentioned it to him and he is embarrassed by it. I'm hopeful I won't have a recurrence.
We had a nice conversation. I didn't see any point in hammering him about the wire. My read on it is his wife mentioned it to him and he is embarrassed by it. His wife joined also and was also very pleasant. They are in their late 20's/early 30's. He is an electrician for a railroad. As I said, they are working hard on the house. (The house had some serious electrical issues as in no junction boxes which was the first thing he fixed.) I also watched closely how he interacted with his wife and children. He was kind and respectful. He strikes me as a good dad and husband. When I was young I made some mistakes (heck I still make mistakes, just no real big ones.) and learned from them. I'm guessing he is also learning and that if it was him that he won't do it again and if it was a visitor, that he'll see that they don't do it again. Time will tell.
Again, thank you all for the suggestions. I'll let you know how my next attempt (this coming weekend) works.
