Why garden snakes are dangerous?

Garden Grass Snakes also known as Garter Snakes (Thamnophissirtalis) can be dangerous.

Yes, grass snakes, not rattlesnakes. Here's why.

A couple in Sweetwater, Texas, had a lot of potted plants. During a recent cold spell, the wife was bringing a lot of them indoors to protect them from a possible freeze.

It turned out that a little green garden grass snake was hidden in one of the plants. When it had warmed up, it slithered out and the wife saw it go under the sofa.
