"that spelling of centre " Oh... cen-tree. We say cen-ter and spell it like we pronounce it. ;>)

Joe... as I said, Pennsylvania has this series of curves built into the topography, so that even when you aim in one direction, you end up being shuttled off to the side. You gotta give up a 'sense of direction' and go by highway signs & maps. In much of Kansas you can go by dead reckoning, but not in Penn. (I had to find Johnstown a few years ago, going counter to those natural curves. It was interesting)
