Not my day, but could be worse...
On the way to lunch today, I got to drive over a collection of reflector material. The car in front of me was kind enough to nail a rubbermaid container that (presumably) was full of turn signals. I think I navigated through without cutting tires.
On the way back to work, I narrowly escaped hitting a 5 gallon bucket of stain deposited on the road way by an El Camino. A metal bucket. On 183. You may be asking yourself "How does he know it was a bucket of stain?" Ask the boor bastard in the Camaro that was tailgating me...
