I've seen a lot of tragic things from Nam, the middle east, and right here in the USA.
Motorcyclists run into head on by an old man on going the wrong way on a divided 4 lane, by the time we got there (flying a medical helicopter) the blood had actually congealed on the road surface, one died, last i knew the other we flew lived.
A dozen country road, single vehicle accidents, hitting a pine tree, some alive, some dead.
Car accidents with a family returning from Disney World, two little ones in the car, tragic
When you see this stuff, you can relate to your own children, parents spouse etc. it works on you.
But some of the above were not doing anything wrong, some were killed by some other dumb A** not paying attention or doing something they shouldn't have been like texting, talking on a phone, eating, putting on lipstick, brushing their hair what ever.
The stuff they do is never going to stop, probably just get worse.
I factor some of this into my rides. Being retired, i can choose the time of day the route etc. Remaining situation-ally aware of what is going on around me.
But all it takes is one sorry A** coming the other way at the wrong time.
Tomorrow, full sun, 50 degrees, light winds, and i will have my leather on, including chaps and cruising down the road, keeping an eye out, but enjoying the ride.
