The wind turbine blade as in claim 1, wherein said attachment bore structural member is configured in said spar cap. 6. The wind turbine blade as in claim 1, wherein said attachment bore structural member is configured adjacent and against said spar cap. 7. The wind turbine blade as in claim 1, further comprising a cradle configured for engaging the handling mechanism and supporting said blade in said leading edge-up configuration. 8. The wind turbine blade as in claim 1, further comprising a plurality of said attachment bores spaced longitudinally along said spar caps in each of said pressure side and said suction side. 9. The wind turbine blade as in claim 8, wherein said plurality of said attachment bores comprise structural members formed in said spar caps. 10. The wind turbine blade as in claim 9, wherein said plurality of said attachment bores comprise structural members disposed adjacent and against said spar caps. 11. The wind turbine blade as in claim 9, comprising at least two said attachment bores on each of said suction side and said pressure side, said attachment bores equally spaced on opposite sides of a longitudinal center of gravity of said blade. 12. The wind turbine blade as in claim 1, further comprising a cap member configured for insertion into said attachment bores, said cap member having an upper surface that lies essentially flush with said pressure side or said suction side. 13. A method for handling a wind turbine blade during any one of a transportation, installation, or maintenance procedure, comprising: attaching a handling mechanism into attachment bores provided in a pressure side and a suction side of the turbine blade; and,lifting the blade or supporting the weight of the blade by engaging the handling mechanism,wherein the attachment bores are located such that the weight of the blade is borne by a turbine blade spar cap. 14. The method as in claim 13, comprising inserting a handling rod completely through oppositely aligned attachment bores in the suction side and pressure side of the blade. 15. The method as in claim 13, comprising inserting an individual handling mechanism into each respective attachment bore in the suction side and pressure side of the blade. 16. The method as in claim 13, comprising transporting the turbine blade in a leading edge up configuration by suspending the blade in a cradle that is engaged with the handling mechanism.
