When the meek inherit the earth, the box turtle will surely be king. Introvert of the underbrush, Mr. Milquetoast of the Meadow, his carapace is his castle. If he doesn't stick his neck out past the drawbridge, he won't get involved. Like a man with a mortgage, though, he can't get his house off his back. A roof overhead is handy when the towhees next door dump their leaves. When crossing a four-lane highway, though, wouldn't you like to have left your house at home?
