Thanks for the replies guys.

We've got property further north, along Red Oak Creek, but we'll come down to the Millrock access in the summer when the creek level gets pretty low. But the cabins I was talking about are the ones located on the north bluff, right at the access, that bikehikefish was talking about. I'm sure there was probably a town somewhere around there and that the MDC area was probably just the local ford. In fact, there's a surprising number of farms and homes along Millrock road. I just can't find any historical references to the area.

12hrs on that stretch from H to Millrock would be quite a feat! The river does wind a bit through there, but I'm sure the beer hampered swift progress for most of the journey.
