Welcome back, @
tjspiel! I'm in a very similar boat. I'll be back to my cube 3-5 days a week... at some point. Delta and Omicron pushed things out.
So I've been doing "commutes" to get bike rides in as much as anything. It's weird to be standing in the cube in bike clothes, with hardly anyone else around, doing what I could have done from home, but I need the exercise.
