I just received a phone call from my son, he works for a company that does turn-arounds in refinerys all over the country. He was at the refinery in Pasadena, Tx today when one of the worlds largest cranes collasped killing 4 workers and injuring 7, he was about 100 yards away and saw the whole thing, he was very shaken up when I talked to him, he was to be working in that area where the crane was once they got it set up. I have and will always worry about the work he does in such dangerous places.............I think he will think more about what dangers are around him now............Our prayers go out for the families of those killed and injured.
