Thoroughfares

City setting implies the presence of roads, so they're not particularly interesting target for this tag.

Examples:
* Roads that can be automatically followed (as in, give character instruction to follow a road east and they do so until something interesting is encountered)
* Roads that improve travel speed (don't have to deal with thickets and such, fairly even passage, etc)
* Roads that lead from one significant location to another (as opposed to some vague stretches of trails that start from nowhere and lead nowhere)
