Here's your sign, deer handler:
1. Newer "soft" bumpers on cars aren't effective in killing deer at point of impact thus deer can travel far before dying.
2. Deer are evolutionary cousins to elephants. (antlers are tusks)
They share the same trait of going to "dying yards' as elephants do, when faced with old age.
3. New road treatment compounds using sand/salt-based chemicalscause the tongue to swell and asphyxiation follows.
