Two Decades

 ...of Peace, Love and Marijuana:

 "This is Seattle Hempfest, the largest annual pro-pot event on the planet. Since its inauguration in 1991, tens of thousands of people from all over the country and the world have been coming each August to hang out, listen to speakers (including both of us this year), catch a few bands, and scope out acres of booths hawking everything from black-light posters to cannabis-themed sex aids to the Libertarian Party. By an all-too-rare yet inspired treaty, the organizers of Hempfest keep the place clean of garbage, booze, and obvious drug sales while the Seattle police and (one presumes) narcs of all stripes turn a blind eye to the open use of pot by one and all. If Seattle Hempfest is a vision of what the world will look like when dope is legal, that world will be peaceful and polite."
