The ruling spends just one word, "plywood", on the most important part, but goes into great detail and updates about trivial air gaps. It just doesn't make sense!

Al - I'll bet you a dollar to a doughnut (no Krispy Kreme please) that a 35" slab of our plywood will take that hit.
I'll take your bet

In 07 we snapped our front bumper 3 times, including once with 4 pieces if 1/2" angle aluminium. It took less than 30 seconds to snap it and we couldn't move faster than 6'/sec.

* Bumper was unsupported across 35" of frame giving a 1" space behind it.
