Funny you should ask.
Just Wednesday night at 8 PM, I was creeping along (30 in a 30 -- with a pickup truck on my bumper), when I rounded a corner and a limping deer appeared in my headlights! He was right in the middle of the road. I was nearly rear-ended by the pickup.
Flatlanders complain about NH's "low" speed limits, but I'm seeing the wisdom in them.
(Once, though, I encountered a wild boar while going to lunch in downtown Miami, Florida!)
A honk on the horn sent the deer limping into the woods.
(They don't seem to notice the car/headlights, but critters
always run from the horn).
