At last! Ann and I head out for our first full week off in two years. Our destination has been tempting us for years: the Ruby mountains. We get on the road early so we can get a few miles of hiking in before nightfall. Most people hike this trail northbound, but we’re bucking the trend. We’re not even sure whether Ann’s parents will be able to pick us up at the other end. Some cell phone signal or trail fortune will be needed to get us back to our truck in four days.
