Mark,
Condolences for your loss.
When you're able to, do take the time to celebrate what a great man your father was. Thank him for passing on and (more importantly) sharing his passions with you. What a wonderful legacy to have given you the gift of an appreciation for motorcycles and a full life. Can you imagine how life would be without the wonderful gifts he passed on to you? I'm sure you feel his presence every time you participate in an activity he taught you to be passionate about. He now lives on in those wonderful gifts he gave you.
I barely knew my father, and he died 10+ years ago. There was a time years ago where I spent a fair amount of time with my son riding mountain bikes, riding ATVs in the desert, camping, etc. However, he's now married and raising a family of his own, so I rarely see him. I think he'll treasure the good times we've shared together, and I hope he does the same with his kids.
This was a heartfelt tribute to your Dad. Thank you for sharing it with us.
Rick
