This is a wonderful new feature and I especially like the ability to add courses over the years and change the list as needed.
My questions marks are Pebble and WeKoPa. I know you are able to walk and carry at Pebble, but I question how many really do so. Nevermind that the rest of the vibe of the place is at odds with the "custodian" vibe Ran wishes to champion. It's quite busy, ungodly expensive, hard to get on unless you're a guest at the even more ungodly expensive resort, etc. It's a nice walk, but it's so far gone from being the kind of place where you feel like you can go out and play golf (or play 36!) that to include it here seems very strange indeed.
WeKoPa is perhaps a little closer to the ideal, though in 10 years and probably 25 rounds I've played there I've seen, I think, one other person walking. To be fair, I haven't been walking in all of those rounds, only the ones during the cooler season. I recall when they opened, they made more of an effort at making walking an option. They even had push carts by the first tee. Those haven't been around for some time now, that I've seen. They aren't offering a different rate for walkers or anything of that sort either. Desert Forest seems to have a better walking culture, from my limited experience there. On the other hand, that's a private club and I like the idea of pushing a public course when possible, and WeKoPa is a significantly more playable course as it is much wider. Again, in the end, I love WKP, I think any visitor to Phoenix should check it out as among the best possible examples of what desert golf can be, but it is still very much resort golf that defaults to guys meeting you at the bag drop and sticking your bag on a cart because cartball is the default assumption. I find it hard to believe it's top 147 custodian of the values championed here, as good as the course and the walk is.
