Wow, thanks for all the info Harv. I actually am not using used drill stem, but rather reject .190 wall 2 3/8 pipe (found it at a place called Texas Tubular in Lone Star for 79 cents per foot. Sounded like a pretty good price based on what I had seen, and was actually cheaper than lots of people are selling the used stem for.)
I have never heard bout it being radioactive/w3tcompact/icons/shocked.gif, magentized sure but radioactive, YIKES... I see lots of people using it, perhaps they know and think it is some advanced form of hot wire/w3tcompact/icons/laugh.gif, but I bet that everyone is ignorant of that fact (like me).
I have considered using either the v-mesh or the woven wire fence, but I will tell you why I think I want the sucker rod (I have planned to use 7/8" rod). Most of the fences I have seen around here which have the pipe and woven or v-mesh wire really look awful after a couple of years. It seems that most horses like to think of the mesh as a wonderful scratching wall. They all seem to bow and sag all over the place from the horses rubbing on them so much. Perhaps you have some tips on how to keep theses fences from stretching, sagging and bowing? Perhaps posts every 4' or so might help but wow would that be alot of posts.
I sure do agree with your sentiments about horses being able to hurt themselves in unique ways. It seems that they have a real knack for finding the one thing which you have not padded, braced, fixed, moved etc. and making the worst of it. I see lots of people round here fencing their horses in with barbed wire and / or t-posts. Scares the dickens out of me, especially the t-posts. I have seen some of the damage a t-post can do to a horse, and to me, it is not worth the $$ saved on the fencing.
