I love walking in the fall in New England...the cool air, the foliage, its amazing. I recently played my home course with my 4 wheel push cart on what is a very hilly course. It was brutal, pushing a cart up the hill, trying not to slide down on downslope made it tough to use the cart...legs were burning. I played again the next week with my Scotty Cameron Sunday bag and walked with ease, it was amazing (other than having to rest my bag on the ground). What is your opinion on this when walking...light bag vs push cart?
