You'd think that we'd remember all the effort we took to put our bikes on the roofs of our cars, but just in case, use our bike roof rack reminder.

Bikes on roof. Avoid smashing them! 

This is my second Subaru. The first one I trashed running my bike into the front of the garage. TWICE. The bike was ok. The garage, not so much. My car's rain gutters, where the rack was connected, were ripped completely off. Yikes. Now when the bikes are on the roof, we sit down, peel our window cling reminder off it's backing (I keep mine always on the side window - ready to move to the front windshield), and then we smooth it on right underneath where the oil change tag is in the left, upper corner of the windshield. When we get back SAFELY. We unload the bikes and put the cling away until the next ride.
