In March, when our work was placed on hold the first time, we were at the start of the growing season. It was easy to walk the trails each week and capture photos of plants as they emerged and bloomed. That, and the occasional guerilla garlic mustard assault, was a big piece of outdoor play back then.
This fall it's been afternoon walks, sometimes evening walks. The Cal-Sag trail is a good escape. I've ridden it on my bike numerous times, but I see more when I walk a new section. Recently I stumbled upon the inlet to the canal from Stony Creek, saw small trees planted when the fish ladder was put in at Mill Creek, later caged to protect them from deer rub.
Other close-by locations are Lake Katherine and Arrowhead Lake, both in Palos Heights. They help keep me connected to the outdoors which is essential in these times.
