This is kinda funny after the anger subsided... I have two skb x-racks (10 to 10 3/4" deep) and they protected my head from damage when I got home from vacation last year I accidentally left the rack standing on the driveway, behind my car, for several hours while I took a nap to recover from the drive home. then I had to leave for work or church or something. got in my car started backing up and heard this horrible scrapping sound from underneath the car. I had to jack up my car to get the rackout!!! Rack was scratched, feet where worn off, but HEAD WAS FINE!!! Thanks SKB!!!
