I don't think your garden will attract snakes. But you do live in an area with snakes. You never know where they will pop up. And usually, they won't be hiding in the bushes, they will be taking a sun bath on your concrete/asphalt/gravel path.
But the rule is, never put your hands or feet where your eyes haven't been first. I understand that copperheads are a little more aggressive than our west coast rattlers and sidewinders.
