I'm not too proud to call for a strap, just won't ever call for strap-on.
Maybe the shackles are what they used to try and bust my neighbors truck window. They must be pretty weak as they couldn't break it to steal his work phone and GPS in the console.
The only thing trackable is the iPod nano that was in my glove box. Had the serial number so maybe they'll try and pawn it. Doubt it though.
