Interesting.
We were at The Burrowing Owl Winery, and while it looks awesome from our pov, I had no idea that most of the "working structure" is actually underground.
Our little Okanagan Valley has become something of a little Napa Valley. The entire Valley is now carpeted in grapevines from one end to another.
It's pretty cool, and we have been trying very hard to become educated "wino's".
