Somewhere between Charles Barkley and Rory McIlroy. 
I offered earlier arguments against your pursuit down this road that can be best chalked up as a generational difference in thinking. I now offer you my best wishes for enjoyment in your new “golfer’s man cave”. A well earned retirement gift to yourself. Take care to take care. There is a reason the senior pro men only play 3 day and not 4 day tourneys. Just as we have only so many miles in our our joints for running, there are only so many back and downswings to our game.
Build started. Put down the jigsaw foam flooring, then some turf, laid out all the enclosure parts, and will assemble that tomorrow.
You are clearly not training enough if you have time for golf. You need to get in the pool and on the bike more. Forget about golf, such a waste of time for very little fitness gain.
I’m retired. I can do both. 
Just have to set up the electronics. Will do that in the next day or two. Turf wasn’t working. It would scrunch up whenever something moved. I might just plop a little 8x5 piece inside the enclosure.
No 19th hole set up?
