I stopped by Tour 3 a couple of weeks ago to hopefully get better shots of the water hole. I forgot there was a drainage ditch along the road, so I wasn’t able to get super close without damaging my shoes. I’ll have to take that into account next time I go. I really want to try and get right up to the edge of the water at some point.
As you can see, the barrier retaining the green is still in good condition. I’m sure the water has been picked clean of golf balls over the years. It would be interesting to try and get onto the green at some point, though that’s where the vegetation is the thickest.
