Seems like some things are just too flukey to try and repeat.
SFO tried to do a 50th anniversary Summer of LOve event in 2017 that turned out to be sort of a dud, although not a total fail.
And today I'm reading that this will be the last year for Burning Man due to the Feds getting all red tapey with next year's planning. Of course I think BM is already over the hill since it's become an expensive caricature of what it once was. But still, the Fed getting involved is just a further instance of it being something Trump doesn't like.
