Of course, the Coronavirus-19 is not called a plague, but it might as well be considered one. Shelter-in-place. No close human contacts. Keep clean. Stay safe.
But there are ways to have outdoor adventures with even staying indoors. You could watch birds from inside your house.
You could look at nature shots.
You could draw or paint nature shots. You could write a memory of an adventure you had. You could read about unfamiliar adventures in books.
Whatever your Indoor-Outdoor adventure may be, stay safe.
