Across the Tahoe Truckee region, a new trend in home design has become more popular in recent years. Door by door, window by window, pairs of wires are strung between brackets and hang across the threshold. On the front door, a yellow sign hangs with a warning about an electric voltage.
A decade ago, the electric wires were nonexistent. But now, in some Tahoe neighborhoods, the vast majority of homes are outfitted with them. The wires serve a very practical purpose: They prevent bears from breaking into homes.
