Trillian Poliak

I don't have a lot of info but a friend of mine told me that there is a HUD (or was) that pings GPS points on the map. And you start this race in a car, then get in a boat, then get in a car again.... and at the end there's some cool party. There is NO amount of googling that is helping me find this so I'm reachin out to the SL hivemind. Help ♥
