18 wheelers are the WORST for rocks and shit.
I went to an HPDE event at Poconos Raceway. It rained halfway through the day and all kinds of rocks and dirt were on the track. I was sure I was gonna get a rock through my headlights or windshield but I made it through unscaved.
30 minutes later on the PA Turnpike....BAM! Nice big friggin chip in my windsheild from a rock kicked up by an 18 wheeler.
