There is something I love about finding a snake living in my garden. First off, snakes are, simply put, awesome. Secondly, the fact that I have helped to make a habitat that some reptile wants to call home is very satisfying. And my kids love snakes. The excitement of catching one and then adjusting to holding it, and calming it down as it wriggles between your fingers for a few minutes before carefully placing it back in its habitat is quite an experience.
If I were ranking cool things you find living in your yard, a snake is right up there with frogs, a notch above salamanders and toads.
Not cool, however, is looking in you wheelbarrow after lifting and dividing a huge clump of grass and finding half a snake.
