I have an '05 Mazda6 wagon. Recently had a Yakima roof racks installed, and have a Thule kayak carrier. Got the Kayak all rigged up in the carrier, and the final step is to secure the bow/stern of the boat w/ties attached to the tow hooks. WELL...we looked all around and can't seem to find any tow hooks. We found one hooky, circle thing under the rear right bumper...but the manual says not to use that for tying down. I can't find any mention of where to find them in the manual. Do they even exist?? if not I guess we take the chance of unsecure bow/stern. Anyone done this kind of hauling w/ their wagon??
