Why are there so many speedbumps on this road? is a question asked whenever driving on Kyle McDaniel's road (117th Ave). The phrase was first uttered when Al Luchini and Adam picked up Kyle to go to raquetball. While driving up the hilly road, Al noticed there were at least 5 speed bumps in a quarter mile distance. After picking Kyle up, Al asked him "Kyle, why are there so many speedbumps on this road?" To which Kyle responded, "Because people fly down that hill."
From then on, whenever Al drove Kyle home from racquetball, Adam would ask Kyle why so many speedbumps were on his road.
