For Driftwood players who have a hard time finding those crates. I edited a map top down screenshot from the Devs and marked where I found them in case anyone else was having a tough time.

About the Game
In Driftwood, you’ll experience high-speed downhill longboarding as an aerodynamic sloth. Drifting is the name of the game, as it’ll help you strike the perfect balance between speed and control. Drift through tight corners to avoid collision with cars and obstacles, and perform wicked tricks as you take in the beautiful landscape around you. These tricks will help you score points, which will unlock new boards that can be combined with various wheels for diverse skating styles.
