I'm not making an entry (the office is 5 feet from the bedroom currently), but wouldn't it make sense to list days commuted? For example, back in college when I lived 2 miles from the academic quad I didn't commute very far, but I did it year round through rain, shine, snow, and sleet. I knew plenty of commuters who lived 5 miles out, but never rode in between Thanksgiving and the start of Spring Quarter.
