I know, right? How much would it cost to hire security if everyone is still paying dues? I know the course that @NM Golf is at has hired security to keep the yahoos off so we should do the same.
My golf mat just arrived so I am going to set it up and hit a few in my backyard!
Most metronome apps have a "Tap Tempo" feature. You can do the drill without the metronome and get a feel for the rhythm by either counting or making a beep or click noise when the putter crosses the low point. keep that rhythm up and tap it into the metronome as a starting point.
