Answer
Go to the North or South Pole, where the radius from the rotation axis is the least.
Work Step by Step
The linear speed of a particle on a spinning object is $$v=r\omega$$ where $r$ is the distance from the axis and $\omega$ is the angular velocity, which never changes. Therefore, to minimize linear velocity, radius from the axis of rotation must be minimized. The point that is closest to the axis of rotation is the point at the top or bottom of the globe, the North or South Pole.
