We had a safety issue because other players are concentrating on their putting and are open season for errant/skulled/bladed/shanked chips. To mitigate thesafety aspect, we would paint al line abourt 3' off the collar from within players could chip. Outside the line was forbidden. We had a short game area for those wanting to practice longer shots. Because there was the short game option, the golfers would follow the rules. But, I fear that, without that option, it would require a lot of policing.
