What is the difference between a road and a street? It is not a question of size (some urban streets are wider then country roads). A road heads out of town while a street stays there, so you find roads in the country but not streets. If a street leads to a road you are heading out of town. If a road turns into a street you are heading into town. Keep on it long enough and a road will turn into a street but not, necessarily, vice versus (a street can be an end in itself). Streets must have houses on either side of them to be streets. The best streets urge you to stay; the road is an endless incentive to leave.
