Trianglia is a jacked-up island where no road has a dead end, and all the crossroads are "Y" shaped.

The young prince of Trianglia mounts his horse, and is about to go on a quest to explore the land of Trianglia. He gets to the road by his palace, when the mother queen comes out and shouts:

"But Charles, how will you find your way back?".

"Don't worry Elizabeth", the prince replies, "I will turn right in every second crossroad to which I arrive, and left otherwise. Thus I shall surely return to the palace sooner or later."

Is the prince right?

(From http://www.ocf.berkeley.edu/~wwu/riddles/intro.shtml)

assuming all the roads are straight he would have to continue turning right at each crossroads, or left at each to circle back, otherwise he will keep on a straight line away from his palace seeing as there are no dead-ends and assuming all the roads are a straight path.
