This is outside the Southern Rockies, but M. and I are in Salem, Massachusetts right now, where a Boston television station carried this report of a man fighting off a coyote.
Maybe those Eastern coyotes really are more wolfish than ours!
Fortunately, brave doggies showed up in North America at least 10,000 years ago, according to some new research from Illinois. Were they pulling sleds? No one is sure.
