Being cool is essential. A vocation. A mission. Since I've been on the planet, the Liberals/Progressives have been winning the "Culture War," even as the Conservatives, the Retrograde Forces of Backwardness, have a stranglehold on our Politics.
It makes for a whiplash kind of existence. The constant pull from cool to not cool.
What is Cool has stayed pretty consistent over time...
Pot. Medicinal and Otherwise.
Jazz. Rock. Country. Blues. Folk. Classical. Polka.
