There were maybe 3-4 other cars at around 4 p.m. The others left, then I saw two owls on the far side of the field come up and do short flights spaced.

Later, as cars started to arrive, one flew and landed on one post and stayed for a long time. The post was far out, so no pictures here. However, when it flew, (as its audience was growing again) it flew back and forth over the trail and landed on various posts on both sides.

By my count it landed on four different posts, at least one of them multiple times.

It flew rather close to the parking lot and the trail.

Despite the cloudy, overcast sky they came out before sunset and at least one of them gave us quite a show. Anything is possible even on a cloudy, dreary day.
