Don't care much about the rain - that will pass or the race will be run later on, no matter what, but I do care about those injured yesterday.
That crash yesterday happened right in front of where we sat a number of years ago at one of the 400 races (I think it was still called the Firecracker 400) on July 4th when they actually held it on the 4th. One driver had a blowout about 100 yards or so up the track from us (we were 35 rows up) and caused a major crash right in front of our section of bleachers, but it all stayed on the track, fortunately.
Watching that tire go through the fence and onto a number of spectators - big ouch.
