I woke up to a flat Friday on my car. I haven't really started round trip bike commuting yet, and I skipped work for a long ride Wednesday so I wasn't planning to be back on a bike so soon, but I figured biking would be more fun than dealing with my car tire, so I rode the ~16 miles in. On my arrival, I saw everyone leaving the building - no power. Boss texted "work from home". So I headed back, very tired. Stopping for a conference call was nice.
