Ed,
I was not thinking of you or GCA outings in particular in my reply. But now that you mention it, I do recall that Barona on Sunday morning was cart golf, and that BarnyF/JakaB and I may have been the only walkers. Considering the wonderful evening and late night at Pete's, plus the dawn start, it was certainly understandable.
My reference was more to a number of area competitive players, many flat-bellied, who make fun of the old farts and bitch about cartpath logos on their ProV1s. Give many of these guys the choice of walking a tournament or taking a free cart, and the cart wins every time.
I am a walker who is content to live with riders. My only requests are that they respect me for my choice and that they minimize the impact of theirs on the turf.
Extreme positions sometimes staked on this site, e.g. no carts, no paths, no markers, etc. and those who disagree are ignorant, full-of-sh.. devils, are counterproductive. Balancing the wants of the customers seems to me to be a better approach.
In terms of this thread, I see tree removal and wider fairways to be a positive regardless of the location of the cart paths. Leaving trees and roughs in place to partially hide the paths is not a good argument. Perhaps by exposing the concrete and asphalt some converts might be gained, and the paths can be removed or relocated over time.
One other partial solution to the cart problem is the pull cart. This has been discussed in some length on this site, but there doesn't appear to be a big push in this direction. Caddies have become too expensive for most folks, and, at times, overly intrusive.
