Rear-ended

The truck is a magnet for calamity lately. I was waiting in line at BJ's in Uxbridge Massachusetts I driver bumped me from behind. Although my parking brakes were all set, my rig was pushed forward a significant distance. I kept pulling on the knobs out of confusion to why I was rolling forward. The offending driver didn't damage my trailer any; and his truck didn't sustain any mentionable damage. This happened the day after my rest area neighbor scraped my tractor.
