Wednesday marks the final day of the 47th anniversary of Woodstock, where over 400,000 people came together for an iconic celebration of peace, love, mud, music and community whose promise still resonates for those of a certain age. With its presence still felt - from a dust-up over a look-alike RNC logo to a new photo exhibit to Sanders/Teachout campaigns that have sparked a kindred sense of possibility - Woodstock "showed the world how things could have been."
