I've never used GeoRuby, but looking at the implementation of
bounding_box for various classes, how about:

  # untested
  class GeoRuby::SimpleFeatures::Geometry
    def point_in_bounds?( point )
      min, max = bounding_box
      point.x >= min.x && point.x <= max.x &&
      point.y >= min.y && point.y <= max.y &&
      min.z && point.z >= min.z && point.z <= max.z
    end
  end
