That's a great idea...Hmmmmmm.
I have a neighbor about ten houses down from us who had a genius idea. He installed a real putting green in his backyard. Complete with flags in the holes. Now there's a golfer who knows putting is key to shooting better scores.. I would like one of those just to go play on.. Actually I could put a few short holes in my backyard.. But then my best friend wouldn't have anywhere to run..
I used to practice short shots in my back yard until I hit a window once and I wuz in trouble yet again...
I finally realized I am too old and arthritic to continue to play and gave my Pro-line set to my neighbor's son in law so he could have a good set of clubs to play with.. He really likes them and my neighbor tells me his game is improving as well. So it was a good thing.. I am too far eaten with arthritis to do most physical things..
