Hot grass fire at Sun-N-Fun

The heat shield cuts down on radiant heat from the CC, but if the
heatshield itself is hot enough and TOUCHES the tall dry grass, then you
still have a fire.

Seems like if there's ANY air gap at all between the CC and shield
that there would be a HUGE difference in temperature between the two.
If there's no air gap, then it's not a shield, really.

I'd worry that tall grass could get caught and wadded between the two
while driving.

During the Minnesota Twins World Series parade, in 1987, a few of the
convertibles caught fire from just that - paper, toilet paper, confetti,
etc. dragged along under the cars.

In 1991 the players sat/stood in the beds of 4x4 pickup trucks.
