Amici:

On purpose, or not, Bob Kramer choose to have this incident occur immediately 
across from the TRIUMPH Competition Paddock, which was just down the road 
from Turn ONE.  It was spectacular.  To say, "...a couple of fire balls" is 
just 
not very descriptive.  For about three seconds, the entire bottom of the car, 
and thirty feet to the rear was engulfed in flame.  Too bad someone did not 
catch this on tape, as it was SPECTACULAR.  Bob was sharing a stall in my tent 
for the week end.  So we had lots of visitors rushing down to see the red TR4 
with holes in both sides of the block.  All but Kas, that is.  Kas didn't rush 
down to see it.  He said, "I've seen these holes before!"  Bob's got a great 
attitude, and his enthusiasm was not diminished.
