As the roller coaster reached the top, the momentum sent it rushing down the track. Ben threw up his hands and yelled "Woohoo". Holly was having fun, too, but was too grown-up to show her excitement.
This is my entry for IF-Momentum. I created this illustration a while back and it was from a photo of my kids on a rollercoaster in New Orleans City Park. We went there on family visits when we traveled from Texas to Louisiana. The park is still recovering from damage, although we haven't been back to the park since Katrina.
