The 'Custodians' list is one of my favorite parts of this site and is a north star of sorts when considering the GCA ethos of thinking and evaluating architecture. In addition to Ran's criteria which I wholeheartedly cosign, I would add an admittedly subjective addendum that is "courses that I find my mind drifting towards the most."
I keep a Google Map of my own personal custodians list. So far there are 8:
Southern Pines
Inverness
Blue Mound
Cedar Rapids
Brookside (Canton)
Pasatiempo
Culver Academy
Pacific Dunes
