Don’t get me wrong, I’m all for interstate commerce, but for the life of me I can’t understand why, when it comes to trade between North Carolina and Virginia, it always has to be a one-way highway. During Prohibition, for example, North Carolinians had to drive across the state line to buy liquor. Later in the century, we had to drive up to the Old Dominion to buy lottery tickets, cheaper gas, and wager on horse races. In recent times we also had to travel into Virginia to buy marijuana. And over the past year and a half, those of us in the Piedmont have gotten into our cars and driven to Danville to play blackjack, poker, craps, and slots, first in a temporary casino, and now in a permanent facility which opened on Dec. 17.
