Your first instinct might be to check the Sunday schedule. Don’t. That’s a trap. On Christmas, most cities run a special schedule that is a ghost of a Sunday timetable. It’s like a Sunday that skipped leg day.
Buses show up, but they’re shy about it. You’ll often get one bus per hour, if you’re lucky. And by “lucky,” I mean you’ll be standing at a cold stop, doing a little dance to stay warm, wondering if you hallucinated the whole plan.
Some routes just don’t bother. They take the day off. They’re at home, probably watching Die Hard and ignoring your text messages.
