One of the challenges we all have is keeping in touch with our netwark of associates. I have always found it a challenge. Harvey had many neat way of keeping in touch. One was if he read an article that he thought some of his contacts would like to see he would mail it to them with a little note attached saying "Thought you might find this interesting. No acknowledgement required. Harvey" I recall he had this as a hand written note which he had printed in blue so it looked personal. Again simple but profound.
