Haven't driven Grattan enough this year, it's such a fun track! My goal for the weekend was a sub 1:30. While I had a handful of laps with the potential for sub 1:30, I ended up running into traffic every time. According to TrackAddict, the car and my current skill is capable of a mid 1:28, so maybe next year!
