Mike - I do understand them which is why I recognize that what happened to 6x6 can happen. It's this same understanding that allows me to recognize that his experience will not likely be mine, yours, or the next guys. Call me statistician, an awnry Scot, or a cantankorous Cherokee, just take your pick, I do like to understand the context of things, the likelihood of other things, and so on. If that rubs folks the wrong way, just realize, I don't mean anything personal by it.
