Cool off and ride!

"Everyone in Baltimore is hot and sticky, from little Hazel playing on the slide to the grandma knitting on the porch. So when evening comes, they all jump at the chance for a little 'cool off and ride.' The whole neighborhood--from the Taylor twins to Grandpa, and even the dog!--piles onto a breezy homemade roller coaster, a city trolley!"--Publisher. Includes an author's note and information on the Baltimore Cool Off and Ride Program.
