I'm so sorry to hear of these things... theres a few things to keep in mind, as I see alot of folks waffling on weather or not to ride.
Im not a bible thumper, and I haven't been to church in a long time..but I believe in God and the fact that Jesus dies for our sins.
When it is your time for God to take you, it is your time. It matters not what you happen to be doing. IF some of these folks that get taken from us while riding were at home, or at work, or driving a car, they still would have been taken by God. Do not stop living and doing what makes you happy and fulfills your life. When it is your time, it is your time, there is no other way.
The only other way is Suicide, and all folks that choose suicide are choosing to send them self to
for eternity.
We will see our fallen friends on the other side, when its our time, cause were all dying, some just sooner, some later.
