When I lived in California, I'd often meet up with my friend Susan and hike the hills of Marin. Situated just North of San Francisco, Marin has some of the most beautiful trails -- in the spring, there'd be boisterous waterfalls and in the fall there were dry and humble hills. I owned a tattered hiking book that covered the region and over the phone the night before we'd meet, Susan and I would eagerly decide on a trail to tackle. The funny thing about the book? It wasn't at all accurate. It wasn't fact-checked. We got lost each and every time we used it. And for some reason, we kept coming back for more. I'm not really sure why, especially considering I'm not someone who favors getting lost off the beaten path just for the heck of it. Repeatedly. But I do know that, because of the poor directions, an adventure always seemed to sneak into our afternoon hikes. The book got us to the trailhead and then about halfway through, we realized we were very much on our own.
