"Retrograde" Neuman ? !! Your dearth of historical/scientific knowledge verges upon fantastic !

We, as a nation, were extremely fortunate Black Canyon Dam was built ! It provided power to essential war industries at a critical time. ( Not to mention providing critical mining/tunneling development/expertise. )

Of course we could dynamite it, ( and other downstream dams) returning southern CA to the "dark ages of its Mexican heritage". Just think of it. Tourists only able to view "Hollywood and Vine" by daylight ! Or only see the impressions of the stars in the same time frame ! No traffic lights. No police responses. No cold beer, domestic lighting, food, etc.

(Don't forget the CA's "energy resource controllers have effectively shut down in-state generation of electrical power. )

Yeah ! Go aheAd and blow them suckers up ! Mech
