"If you have not seen the news, we had a wild ride here in the North Bay this morning. There was a 6.1 earthquake centered in American Canyon just south of Napa, about 28 miles from here. Everything is fine in Santa Rosa, but Downtown Napa is a mess. Damaged buildings, broken water mains, downed chimneys, and several injuries. That was the largest earthquake in this area since the Loma Prieta quake during the 1989 World Series. Sending well wishes to our neighbors in Napa! We are okay here."
Head Casers can sip easy, it would appear.
