I got coons too, a lot of em' and I ride in dark o' 30 everyday.....
When driving in the dark I slow as well, stay in the center of the road, as we are heavily forested, trees coming to the edge of the road, etc, and I watch for the glint in their eyes. I look over my windscreen and visor up if the conditions allow it.
I aim for their butt, as they just won't reverse their course of travel....
Deer, they will, you just gotta take each encounter on its own condition...
Slow, and SLOWER, seem to be the best course of actions, and knowing their routine, like feeding and rutting, etc.
Even with all this caution, it is still Russian roulette, as we loose riders to deer strikes ( not all be fatal, but at higher speeds, the body damage is often enuff to have to give up riding ) yearly...
It is ALWAYS on my awareness and I NEVER relax my guard.
