What defines the bumper zone this year?? In the past, I remember it being from 1 to 7 inches above the ground (2010 excluded. Bumpers were higher that year), but I cannot seem to find where the "bumper zone" is defined in the manual.

Both <R01> and <R29> reference a "bumper zone" for those who are wondering. Please tell me that bumpers are going to be like the height limit last year, waiting for Q&A to open to ask a question that will greatly impact designs...
