I started using a Go Cart during my recovery from an appendectomy.
Have also used a jogging stroller.
Sometimes I carry a Revo Carolina with quads.
Which option I choose on a particular day depends on where I'm playing and how many rounds I intend to play that day.
If I'm planning on 27 holes or less, I'll usually carry the Revo.
If I'm planning on 36 or more, I'll use one of the carts.
If the course is very wooded or hilly, carts can be more of a pain than a help.
If I want to carry extra stuff (cooler, water, clothes, camera equipment, etc), carts can be a real benefit.
Carrying a bag helps strengthen my back and reduces my lifelong back issues. The back issues came back after I used a Go Cart exclusively for a year. That's why I alternate with carrying a bag.
Use a cart if you want.
I don't understand why people criticize others for using a cart.
It's a choice, just like the disc you throw and the plastic you prefer...
