One evening I decided to try my hand at writing a poem for my son, Ethan.  He was 6 at the time and we were both deeply enthralled with the subject of dinosaurs.  

So naturally I incorporated that subject into my literary effort.  Here's the first stanza:  

         "My little boy was pretty sure 

           that he would find a dinosaur.  

           He felt it wouldn't be too hard - 

           he started searching our backyard."

I completed the story, asked him to draw some accompanying pictures and we were off!  

To date, we've collaborated on three volumes of what I call "fact-packed dino-rhymes."
