Good points. I've seen the bug covers. I think maybe a fork-mount system would be a little more stable and a little less noisy than the full mount. I have driven 70+mph for maybe 30 miles, but that's about as far as I've gone, so far. It was pretty noisy,

I didn't think about the vibration, but you're right... not a lot different. I was concerned about the rear-ending problem, but I do see a *lot* of people driving around with the rear-mount racks and that got me thinking. Sometimes it's best to go with your gut
