Before your kids pile in the car to go to a Disney park or Six Flags, you might want to show them this Library of Congress picture of the world's first-ever roller coaster.
It opened at Coney Island in New York in 1886 and cost $.05 to ride. It had to have been a thrill in those days, even though it looks pretty mild by today's standards. And by the way, it went six miles per hour. Note the "Strap Yourselves" sign to the left. What fun! Hope your kids are enjoying their summer vacation. I see 'back to school' sales everywhere so the clock is ticking. Get out there and have some fun.
