Bikes On Top! - Roof-mounted bike racks are great devices. But, they have an Achilles' heel: It's too easy to forget that the bikes are up there as you drive into your carport or garage. Crunch! When this happens, even if your bike escapes major damage, it's likely that the roof rack and car top will be bent or worse. So, it's definitely worth it to avoid the hassle of driving into things with the bikes on top. One trick that might help is placing the garage remote control in a cycling glove. This way, when you see the glove, it should remind you of your precious cargo. This trick won't work if there's no remote control. Instead, you might place a sign on your dashboard or try hanging a flag on your carport with a picture of a bike on it. Or, mount a mirror on your garage wall that lets you see the loaded roof rack as you pull up. One of these suggestions just might save you major grief.
