I used to always hit a bucket before playing a round. This year the range is closed Thursday morning for maintenance so we just T off. I have kept track for the last 2 months and have shot 2-4 strokes better on the range closed days. I do still stretch and warm up but don't hit any golf balls. My hacking buddies say that I hit all my good shots that day on the range and save the bad ones for the course. By just playing I hit the good shots during the round and not waste them on the range. Is that true?
