Landon Cassill draws hilarious track map of Sonoma Raceway

Sonoma Raceway can be challenging ... unless you take great notes. 

Sprint Cup Series driver Landon Cassill gave Twitter followers an inside look at how he prepares for the 1.99-mile California road course: A hand-drawn track map that includes amazing notations such as "usually lots of dust," "short cut if nobody is looking," and "no bumping please (scary)."

There may even be a bounce house! Best. Map. Ever. 

If you're having trouble reading Cassill's handwriting, here's a little help (starting at the Start/Finish line and going clockwise).

- Where the pole car starts the race

- Super fast part

- Can't see

- Still can't see

- Usually lots of dust

- Not sure what this part is for

- Not sure what to do here

- Why isn't this turn 4?

- I think there is a bounce house here

- More dust 

- I don't remember 

- Short cut if nobody is looking
