I finally did it.....
I drove into the garage with the Palo Alto still on the roof rack.
Damage assessment:
Roll-up sectional garage door - partially destroyed, $590 worth of damage.
Thule roof rack - two tower feet bent, bike tray twisted like a pretzel.
Car - no damage, save a microscopic scrape/rub on the driver side rain gutter.
Bike - slight scratching on the top tube, two partially smashed cable guides, kinked and split rear brake cable housing, torn bar tape, vintage white Selle Italia Flite Ti saddle destroyed (maybe).
Monetary loss of the garage door aside, I figure I'm pretty damn lucky. The bike was only slightly cosmetically damaged, and the car was virtually unscathed. Good thing, too, because it will be up for sale shortly. I find it amazing that the bike took the hit, but other things suffered the brunt of the damage. Apparently the bike was low enough so that the opened door grazed the stem, and when the saddle nose hooked the lower section it tore everything loose and it all came crashing down.
I learned my lesson - roof racks, garage doors, and
me don't mix. I'm done with roof racks.
The garage was repaired (professionally!) the next day. I managed to get a thin bladed pocket knife to spread the cable guides back out, cable housing and tape has been replaced, and carefully applied metallic nail polish covered the scrapes (more or less) acceptably. I was able to remove the split saddle cover, and maybe the local cobbler can fashion a replacement. If not, the hunt will be on for a new saddle - oh, well..... it was getting pretty ratty looking anyway.
I would have taken pictures for you folks, but I was too depressed. All is fixed now, so there's nothing to really see anymore.
