In the Opus Industrial park Criterium series here in the Minneapolis area earlier this year, we had a paint truck make its way onto the one-way traffic course, and start repainting the white lane lines. Coming down the hill to the back straight which averages about 27mph for cat5's, we ecountered orange cones placed in the middle of the road. Some of us were quick enough to veer out of the way, but somoene's veering clipped the wheel of the rider behind them, and sent that person square into the pavement breaking their collar-bone. It was easily the most unecessary accident of the year I had the displeasure of hearing. I think the whole peleton swore at the truck to GTFO the road as we passed by.
