There was a man driving down the road behind an 18 wheeler, at every stoplight the trucker would get out of the cab, run back and bang on the trailer door. After seeing this at several intersections in a row the motorist followed him until he pulled into a parking lot.
When they both had come to a stop the truck driver once again jumped out and started banging on the trailer door. The motorist went up to him and said, "I don't mean to be nosey but why do you keep banging on that door?"
To which the trucker replied, "Sorry, can't talk now, I have 20 tons of canaries and a 10 ton limit, I have to keep half of them in the air all the time!"
It is curious that with the advent of the automobile and the airplane, the bicycle is still with us. Perhaps people like the world they can see from a bike, or the air they breathe when they're out on a bike. Or they like the bicycle's simplicity and the precision with which it is made. Or because they like the feeling of being able to hurtle through air one minute, and saunter through a park the next, without leaving behind clouds of choking exhaust, without leaving behind so much as a footstep. ~Gurdon S.

Prior to 1907, when the United States started mass production of asphalt from crude oil, the roads were paved from asphalt bought from Trinidad, which had a pitch lake that was the world’s first large commercial source of natural asphalt.
