The edge of the town is usually beautiful.
It is usually abandoned too because it is at the extreme end, even the outskirt of the town.
I saw a movie where the edge of the town is a mountain, a very high mountain. After getting to the top of the mountain, you can see the town from a high perspective, quite a good site.
However, anything that has to do with edge require carefulness. People who have bad intention can come from the edge. Which is why the edge should be well guarded.
I have been to the edge of few towns before, and it was cool to see the edge of one town and the edge of another at the same time.
