There's so much old stuff around here that he is basically being called out to perform an assessment every time anyone wishes to build anything.

Where we live now, for instance, there are a handful of burial mounds from God knows when (all plundered long ago), lots of old charcoal pits, a couple of late stone age fish traps in the lake in a corner of our farm.
