Hitler's birthday.........lol The flyer came complete with a 420 back story: "420 started somewhere in San Rafael, California in the late '70s. It started as the police code for Marijuana Smoking in Progress. After local heads heard of the police call, they started using the expression 420 when referring to herb - Let's Go 420, dude!" Bloom reported his find in the May 1991 issue of High Times, which the magazine found in its archives and provided to the Huffington Post. The story, though, was only partially right. It had nothing to do with a police code -- though the San Rafael part was dead on. Indeed, a group of five San Rafael High School friends known as the Waldos - by virtue of their chosen hang-out spot, a wall outside the school - coined the term in 1971. The Huffington Post spoke with Waldo Steve, Waldo Dave and Dave's older brother, Patrick, and confirmed their full names and identities, which they asked to keep secret for professional reasons. (Pot is still, after all, illegal.) The Waldos never envisioned that pot smokers the world over would celebrate each April 20th as a result of their foray into the Point Reyes forest. The day has managed to become something of a national holiday in the face of official condemnation. This year's celebration will be no different. Officials at the University of Colorado at Boulder and University of California, Santa Cruz, which boast two of the biggest smoke outs, are pushing back. "As another April 20 approaches, we are faced with concerns from students, parents, alumni, Regents, and community members about a repeat of last year's 4/20 'event,'" wrote Boulder's chancellor in a letter to students. "On April 20, 2009, we hope that you will choose not to participate in unlawful activity that debases the reputation of your University and degree, and will encourage your fellow Buffs to act with pride and remember who they really are." http://www.huffingtonpost.com/2009/04/20/what-420-means-the-true-s_n_188320.html
