Last week's Open Thread asked readers to name their favorite local brew, with choices such as Port City's Porter and DC Brau's The Corruption getting shout-outs. So it only makes sense to turn our attention this week to wine. Wineries are a great summer weekend mini road trip, and there are plenty within easy driving distance from D.C. Some are notable for their actual wines; others are more of a tourism destination due to their scenic grounds. This week's Open Thread asks, "Which Virginia or Maryland Winery is Worth the Drive?"
