Streetsblog's America's Best Bus Stops Contest is down to its final two contenders. Nationwide, though, the United States have a lot more sorry stops than good ones — and to understand how our top two wonderful waiting areas bucked the trend, we brought in an expert for some game-time commentary.  Today, we're talking with bus stop expert and Transit Center Senior Research Associate Mary Buchanan, author of the indispensable report From Sorry to Superb: Everything You Need to Know About Great Bus Stops. Host Kea Wilson chats with Buchanan about how cities can create — or fight for — the structural conditions that help create great bus stops, and keep them well-maintained for years to come. And then we dig into why America's best bus networks might not have a whole lot of "great" stops at all — but they would have plenty of adequate ones.  Give it a listen, and don't forget to cast your vote in the final round of America's Best Bus Stops by Friday, April 15 at 10am ET.
