it would be hard to pick a "worst" run...probably for me the worst runs were the ones where you have problems with your truck, finding an address, driving thru the snow etc. no fun runs, but i do recall the most embarassing run i can remember.it was in my tractor trailer days.i was loaded to boston, and my delivery was in an old part of town.like many northeastern towns, boston is still using low bridges that were in operation long before trucks were on the road.i had to go under one of them to get to my drop. after unloading, i had to drive the same route, under the same bridge...i had only been driving about six months...as i went under that bridge for the second time i hit the bridge and peeled the roof of my trailer off like opening a sardine can, about half the trialer length. i learned a lesson that i never forgot. the trailer rose a couple of inches after unloading because it was empty. the embarrasment was having to stand there watching all your fellow truckers, guffawing, as they drove by while you wee waiting for smokey to fill out the accident report. incidentally, it came out as a non chargeable accident to me, because that bridge was 13' 6" only if you were straddling both lanes, and i was gratified to find out from the attending officer, that i was not the only one who had hit it that week, didn't help my bruised ego much.
