Walking at night

Thinking about the details that influence my walking routes for the last post here, I also started thinking a lot about how different it is to walk during the day versus at night. A route that is pleasant to walk during the day thanks to its seclusion may feel unsafe at night for the same reason, for example. But more than personal safety changes with the time of day.

Some places that I walk, especially in many of the old neighborhoods that exist in and around Boston, have pretty challenging walking conditions, including sidewalks that are too narrow when they pass by old trees, or that have been pushed into tall, cracked hills by those trees' roots. Brick sidewalks, already somewhat tricky are especially hazardous where they interact with tree roots. And all of these obstacles are even more challenging at night, because those same trees then block the streetlights' illumination of the sidewalk in those areas. This means that when I'm walking at night, I try to choose routes that avoid poorly-lit sidewalks that I know to have obstacles where they interact with trees.

Are there other issues that change your walking habits daytime vs. nighttime?
