Standing in the doorway of Robert’s house in downtown Harrisonburg, I stare at monochromatic misting rain and gray skies. It’s a typical winter day in northern Virginia—wet, cold, and bleak.

“This is perfect weather to curl up with a cup of coffee and read a good book,” I say, turning to Robert. Reclined on the couch in his sweatpants, he looks exceedingly comfortable. “Are you still down to do a hike?”

He nods. “Of course.”
