How about all of the books I studied over the years, in depth, that have now become repudiated "Old Light"?
All of that superfluous "knowledge" I absorbed. We could include the Sandwich Boards I wore for the DC at the Rosebowl in like 63' or 64'. I recall they had a tiny one for me to wear (I was like 4 or 5).
I'm glad no photos have circulated of that ignominious start.
