Out on the course yesterday, it was probably 90% guys who were over the age of 60 and they were all using push carts (for good reason). I was one of the only people out there who were walking and carrying their bags, and I felt good about it. It feels like I am getting more out of the experience, and at the same time I feel like I am the player and the caddy.
I just use whatever tees I am feeling that day. At my favorite local course I usually end up on the white tees, and that has given me a decent level of difficulty but not too much that I can barely get low scores.
I actually ended up having to run yesterday after I played nine holes. I love running with a passion, but getting back into the swing of things after lacrosse ended is what is so difficult. Started with 3 mile quick runs, I'll start working my way up like usual.
