Key kids, let's have a blackout party

In an effort to make "a poetic and direct response to the irresponsible behavior of energy suppliers, utilities, and government officials," some grassroots political groups held what amounts to blackout parties from 7 to 10 p.m. on the first day of summer, June 21. How much sense does that make? The first day of summer is the longest day of the year, so by 10 p.m. the sun will have hardly set. There is not much need for lights, so who would have noticed a blackout?
