Brad,
Perhaps the best thing to do would be to continue this exchange off the message board. If you wish, you can write to me at rtrowt@sbcglobal.net. For what it's worth, I believe "Post Dallas" was located at the top of the hill overlooking the Marble Hill city cemetery. A private residence currently sits there; before it was built, a church was on the site. But I'm sure Cochran's companies also were in temporary camps here and there.
