Kendall responds Have you ever rode down a hill that was so steep before?.
The friend responds No, I have never even seen a hill that was that steep and long before. You've got to be careful Kendall..
Kendall responds Well, we will know from first hand experience to not do that hill again..
The friend responds That is for sure, I am just sorry it took you losing control of your bike for us to know..
