For the record. My home course, Carolina GC (Charlotte) is hilly but very walkable, and we have lots of walkers. At age 69, I'll use a push cart and take 14 clubs, or a "Sunday bag" to carry and take 7 to 10 clubs. It all depends on how my back is feeling that day. Why walk? For me it just feels right, good exercise, and it helps counteract my natural tendency to be way too quick. Yesterday I walked 18 with my push cart, playing with two other members, 67 and 69, both of whom carried, although I do not think the 69-year-old carries 14 clubs. Today I walked the front nine with the same guys before I had to leave for an appointment, and they continued for the full 18. I'll ride in a cart if it's part of an event, or is a practical necessity, like on a residential course. I will also ride in the summer when playing in the middle of the day with extremely high heat and humidity. Frankly, I don't care what others do, or what others think about what I do (walk vs. ride).
