I ride Wasson Way on almost a daily basis. It's a great new rail-trail that connects Hyde Park with Norwood-Evanston here in Cincinnati. The trail is intended for walkers, bicyclist and Runners as a means for exercise, getting outdoors and making the city more connected with out the use of a car.
Since COVID-19 has joined us, the trail has gotten much busier. Mostly with walkers and runners. When it started, the walkers tended to walk in large herds and seldom yield the lane for opposite direction traffic. Now the herds have gotten smaller, but the observe social distancing by walking side by side six foot apart and, of course, still not yielding the lane to opposing traffic as should be done. On top of this, the ones that walk alone tend to have on earphones and wander from side to side. They, of course, cannot hear the "on the left" call and are a real trail nuance.
