The shape looks cool, although a bit narrow. First i thought of Canouan island, which is 30km away from Union Island.
And how fun it would be to have a 'complete' map surrounded by water, something that's never been done (to my knowledge). That's how i got the idea of making one for Assetto Corsa. as i was exploring the globe with Flight Simulator, i flew with a jet from Trinidad & Tobago all the way to Puerto Rico, no gps, just following the flow of islands. Time passed, and one day, out of the blue. since Google map is limited to visit the island. But not being there anymore would prove difficult to get the references etc. I lived 7 years on the island of Cyprus, and really wanted to recreate the feeling i had back there driving the Caterham. Being in control of the whole process of creating a track from scratch, and see how that exercice would work. After helping Phoenix on LA Canyons, and PCH more recently, i always wanted to try and create my own roads.
