No time for a photo, but today at the merge point of two freeways I saw a CHP officer, flashing lights on, parked behind and protecting a small junk trailer. As we got closer it was obvious the hub and wheel had come off the trailer leaving just the stub axle. Somebody forgot the cotter pin?
Seemed to me the only way to get the pickup and trailer to a safe place would be to just order the pickup to drag the trailer as-is to the shoulder beyond the merge, because getting a wrecker in there and hooked up with a dolly would disrupt traffic and likely cause crashes.
