Played my "home" course last week with my son and 4-yr old grandson. As I am looking to "par" all 18 over the challenge, I was able to add another hole as "done". It was #18, a par 4 with water most of the way on the left, trees on the right, huge fairway bunker right about where my ball stops on a good drive. This hole I always bogie or worse. It has been a nemesis, but this time I had a great, for me, tee shot with the driver that left me just short of the fairway bunker I tend to find. A 5i to the edge of the green for nGIR. A quick chip with the 9i for a 5' putt for par. Cannot complain. Still have a number of holes to get on the card as par. Then maybe in the balance of the year, work on an upgrade to birdie on some or most.
I used to have SI joint issues all the time. Mobility and stretching really helped as did core strength. Since I retired in April, I don’t sit that much anymore and my SI doesn’t flare up as much. Sitting really can cause issues.
