My town has thirteen buildings.
Its name has four letters.
Exactly six roads leave the town.
Only one leads to my twin town.
The other five roads are dead ends.
Four of them are three blocks long.
One of them is two blocks long.
Walk carefully in the dead end cul-de-sacs,
Since sharp objects are hidden there.
I love my town, despite the lines
Nearly everywhere you go.
Whenever something spectacular happens,
We have many meetings with our twin town.
What is the name of my town?
