Trout, you got to do all that on a course, or a really good practice facility?

This was at the 9 hole course where I grew up.
It had a practice area where you could hit your own balls.
It was about 150 yards from my back door.

I spent countless hours hitting my old Titleist shags in this area.
Typical routine:
empty shag bag (maybe 75 balls), walk 125 yds and sit the shag bag down for a target. I'd also take my two headcovers. I'd lay them 15 ft. left/right or short/long of the bag. Pace the yardage back to the bag to double check yardage. (you take longer steps going uphill than you do downhill)
Hit several shots trying to make a tight pattern. When focus dropped off, I'd pick up 5 or so and move up 5 yards to 120 and hit at target; then take 5 balls to 130 and repeat.
Hit all the balls. Go pick them up and observe where most stopped.
Repeat at a new yardage.

The area wasn't anything special, except that I almost always had it to myself, and it was so close to home.

I went to the Pelz shortgame school around '93, which inspired me to spend a lot of time working on specific yardages less than full.
The old PVC circular pipe just happen to be a convenient and useful target.

I do think that this type of practice is much more rewarding than the typical driving range practice.
