What the drought looks like: clear sky, a touch of green on the hills, and bone-dry trails. This was at the top of the Seaview Trail in Tilden Park, in the hills above Berkeley, this afternoon. That’s Mount Diablo in the slightly dirty distance. Met dozens of people out walking — more than I ever recall seeing on the trail at once (one reason: it climbs a good 600 or 800 feet from the nearest parking areas, which are more than a mile from the top). We’ve had less than half an inch of rain this month, the month that’s usually the heart of the wet season.
