Semi-trailers stacked like the twin towers.

[Jehu]

I was on the oldest bridge in my home town, the bridge crosses the Snake river. I was standing with many others (a crowd) watching these white trailers being stacked really high. Two stacks rose up from the Washington side of the street. One of the trailers on the top of the left stack was precarious and was obviously going to fall off. I thought to myself. That thing is going to fall and it is going to hurt someone. So I began to run towards the Idaho side of the bridge to safety. I thank God for your insight.
Thanks
