This is another old one. From the later 1980’s or the early 1990’s.
There is a ridge line of dirt. It is brown. Along the top is a ver well made barbed wire fence, the kind with mesh below and barbed wire strung in strands along the top. Though it does not seem to have much purpose. Becuase you just use the tunnel down the hill. I go thorough the tunnel. The people I am visiting are on the other side.
