Awesome! Right, This is the first time I ever dipped into this thread so I’m not sure what’s gone before or what exactly the rules are, but I’ll give it a go.
With the Canadian Grand Prix coming up my challenge is to lay out a circuit entirely on an island. And i’m not talking, y’know, laying out a street circuit in London because London is in Great Britain and Great Britain is an island…
…find an island that’s no bigger than maybe 2 or 3 miles across and keep your circuit entirely on that island. You can use existing streets if you wish.

Pit lane isn’t necessary but nice to have.
