ya bindings were on. high backs put under the starps and all that. bindings were facing down.
thats the only thing i could think off. was it became loos over time or someone tried taking it off but thats realy doubtful. its a thule ski rack. dont know how old or anything. its been on the audi for 4 or 5 months now.
the whole bar and clip came off. heres a pic of what it looks like now. i was very lucky that thas all that happened. i was also always paranoid the first couple times but just got used to it and never even worried about it. it's not going back on the car anytime soon, thats for sure.
