While I was combing the archives to find an answer to some of your questions from the series of old threads below, I came across this brilliant exposition on why Virg decided to look up the cowboys when he did and a highly defensible proposition on why he brought along Wyatt, Doc, and Morg. I also agree wth everything Jeff Morey says. The other main poster in this thread (not KtK) seems kind of lost, but I'm pretty sure that he'll agree now that my response is definitive and closes the case.
