Thanks for the reply. It's hard to even tell where it was in that area. I suspect it was just east of the intersection of HW NN and HW C, but it could be NW of the intersection also. I don't have hardly any history on it either. On this page: http://www.rootsweb.com/~mosaline/familyhistories/casebolt.html Under "Obituary of Phillip Casebolt", Petra is mentioned briefly.
