Right up there with demolishing Fremont dragstrip later known as Baylands. The land then sat empty for 20+ years. I lived in the SILLYcon valley when it was an unspoiled area. Left in 94 when I could no longer tolerate the bureaucratic BS and growth that had turned what once was a garden of eden into hell. I can assure you its gotten much worse and more liberal.
I know more natives to the state that have bailed than people that have move there and some that want to bail but can't financially as they stayed too long.
