Hard for me to do.
Remembered all the holes after 1 round at Merion, PV, Pebble, Cypress and, for some reason, Prestwick and Easthampton. Drew blanks at TOC, RDGC, Shinnecock, Fishers until a second trip around. Still have memory gaps at about every other Top 100 I've only played once (e.g. LACC, Bel-Air, Pasatiempo, TCC, Nairn, TNC, Elie, Machrahanish, Atlantic, The Links) although general impressions are still strong.
Getting better as GCA raises my knowledge of architecture and I'm looking for specific things.
