A couple weeks ago, while driving across central Washington to visit my parents at Priest Lake, ID, I witnessed a true "vacation ender." The family and I were in our 2009 Subaru Outback with a Yakima Skybox attached to our roof, when it became apparent that we were pushing a significant headwind when descending into the Columbia River Gorge at Vantage. It is always windy along this stretch, but the waves on the river were especially large and white at this time. Once we crossed the river, and started up the grade, the wind now came at us from the left. Half way up the grade, I noted a car on the shoulder with the top of their Yakima Box missing. I logged this note away and continued up the grade. At the top, an Acura SUV with a Yakima Box passed us. As the car got 100 or so yards ahead of us, the top of the box flew off and golf clubs went flying all over Intertstate 90. I now thought, "hey, maybe these boxes are not designed for such a strong cross-wind." I slowed down to 55 mph (70 mph is the speed limit) and pulled off the highway at the neaxt exit, fortunately only 1/2 mile down the road. I proceeded to tie down the box, front and rear, with rope, and as I cinched down the rear, the top pulled down onto the bottom: I was going to be the next garage sale. I have since purchased tie-down straps for my Yakima box. I don't know if Thule owners have had similar experiences, but a little rope or a couple straps might prevent someone from finding out.
