And a fat lot of good to someone who came out of the station entrance and turned RIGHT ...as I did.
Which shows a lack of consideration by whoever positioned it for someone unfamiliar to the city. Pretty much everything in Truro involves turning left and so passing the map. But you and many others probably don't know that getting off a train in a new place, be it on business, tourist etc having never visited Truro before.
Locals don't think of this as it comes natural to them that everything is turn left!
