John is one of the most well respected posters here on RCU and any advice he gives should be seriously concidered in my opinion...He gives his time with an honest desire to help..He is saftey orented and that is a very good thing..Many of us have seen some some awfull things that could have been prevented had a person been more saftey concious..A person does not have to be a Retard to make a mistake and get himself or someone else hurt..
