Hey Holt...maybe this will assuage your fears...
I live in a forested area of the Pacific Northwest. We get coyotes. We also get black bears, cougars, and Roosevelt Elk (huge, and could kick you to death), who periodically wander in and out.
No one gets hysterical - we don't bother them, and they don't bother us.
But in the meantime, please keep on the lookout for thrill-crazed chipmunks who might be invading San Francisco!! Constant vigilance!!!
