"Mr. Toad" at Buttonwillow (14 March 2022)"Mr. Toad" at Buttonwillow (14 March 2022)

Buttonwillow has many different configurations; this day used the Race #13 configuration, clockwise (CW) in the morning then counter-clockwise (CCW) in the afternoon. The map is weird because for some reason Buttonwillow Raceway always draws their maps with north at the bottom. It's very disconcerting to see East Loop on what should be the west side of the map.
(Note: Hover over any turn name in the text to highlight it on the map.)
 Best morning lap (CW) (2:15.599) |

Say stuff ...
