So your out in the middle of nowhere,Pope Valley Rd near Napa, where only Pashnit people go and on your left you see this. Hub caps on every fence post and pole.
You get closer and there are even more hub caps.
On the brakes and you make a U turn and this is on your right
And here you are. You knew this place was here because it is an official State of California Monument. If those outside the state didn't think we were crazy this will prove it.
Here is the whole thing.
