I am reading the February 1968 Track and Field News in which there is a page article by Dick Held extolling the virtues of a rubber tipped javelin in high school meets and in practices at all levels. Living in California where the javelin is not a high school event, I don't know how common the use of the rubber tipped implement is. I do know that Amazon.com can have one at your doorstep Tuesday if you order within the next 4 hours and 13 minutes but I don't know how exclusive are they in practice and at the high school level. Are they mandated in the states that have this as an event? A little help here would be appreciated as I am writing a paper which includes this. Thanks
