Vineyard Digs
Seen the Anons digging winery's and thought I would mention an old one in my neck of the woods.
Concannon Vineyard - Livermore,Ca TESLA rd.
Possible TESLA family connections, needs digging
TESLA Coal Mines also in the area/closed to the public early 1800's
Located very near to LLNL, Sandia Labs, Stanford Research
Many vineyards in this area.
