PGA of America, USGA or some entity should step up and provide FREE ball repair tools at every golf course. Provide a large, clear plastic container of these very inexpensive tools, (the slightly bent, 2-prong variety) on the counter where you pay with a TAKE ONE and USE IT sign. Right next to the container would be a stand-up sign that shows how to use the tool to repair ball marks on the green.
Apparently, almost NOBODY carries a ball repair tool by the number of unrepaired ball marks on greens at the courses I've played so far this season. The greens yesterday had back pin placements on about half the greens. I fixed several to many ball marks on every green on the way to my ball or while scoping out putts.
If you guys play courses other than top-tier private clubs where they pay help to fix ball marks twice daily, you know what I'm talking about.
For those of you who don't own one of these inexpensive tools, please buy one and USE it to repair your ball marks.
Thank you from a guy tired of repairing 50-100 or so ball marks during a round of golf. And don't hit me a 'rules violation' for repairing a ball mark other than mine. I don't care. Rolling a putt on a clean line is more important.
