Saddened for your loss, Clay..
My dad was also a biker, mind you,nearly all the guys rode them after the war, he used to ride me on the tank, when I was a toddler, and introduced me to the addiction.
He passed away 8yrs ago come 10th Sept.
Never a day passes without thinking of him / missing him, and a prayer at the end of the day.
God bless your dad, and I'll offer a prayer for him too.
