Lynn has been out of town in observance of her mother’s eightieth birthday for the past several days so I had a weekend to fill. Going to hiking meetups seemed the thing. The first one taught me the importance of carefully noting the meeting place. Just because a prominent trail begins in a county park, do not assume that the members will gather there or that you will hike the whole length of the trail. The Arroyo Trabuco trailhead that I know lies in O’Neill Regional Park. I arrived there shortly before the departure time to find the lot empty except for a sports car and an oversized pickup truck. Only a couple of bikers on their way back from a ride lingered at the beginning so I wondered if I had chosen the wrong date or time. The network was thankfully connectible, so I installed the Meetup app and discovered that I was there at the right time, but — this took awhile to sink in — at the wrong place. The organizer had chosen a spot two and a half miles away, so I hoofed it over a path thick with stones the size and shape of prehistoric eggs until I caught up with the other hikers — who were on their way back.
