I managed to get lost in my own backyard today. I was trying to rediscover places I played as child in Crest Canyon, giddily following anything that looked like a trail. I found hidden canyons, dark forests, grassy valleys, bare mountaintops... and then the trails disappeared.
Eventually I was able to find the trail I'd come on and retrace my steps to the familiar north-south trail. I remain amazed that this rich uncharted world is tucked away so close by.
