Golf Clubs are ideal improvised weapons for dealing with poisonous snakes. Since they're designed to hit things at ground level anyway, they're much easier to reach a snake's head with than a bat would be, and long enough to keep the user out of the snake's reach, unlike most sticks. Even better, the club end can be used as a hook to pick up and move the snake (use a second club to pin it securely) more easily than most tools if the situation is controlled enough that the snake can be moved without killing it.
