Augusta never had trees like it does now...things have gone too far imo. To me the concept of trees at Augusta should be in terms of copse....not fairways lined with trees. I also saw some issues with the best players in the world unable to go at a green when less than five yards off the fairway due to low limbs...thats just silly.
When one really looks at the design Augusta should be considered quite a penal course. Between water carries, forced bunker carries at greens and playing between at greens Augusta is as penal as Oakland Hills and Oakmont. Yet, at least for the best players, Augusta doesn't seem to feel that way while watching. Anyway, that is my main reason for disliking too many trees at Augusta...there is already plenty going to add to the penal side of the ledger. So no, the trees do not make Augusta. Sometimes they enhance the design, sometimes not so much.
For heaven sake...whatever one thinks about the trees...those poxy circles of needles around some trees is one of the most ridiculous things I have seen on a golf course. If I had to get rid rid of every single tree to eliminate that feature I would happily do so.
