first you need to find out where to go on 420, go to parks or govenment buildings city hall, etc. then you would have to tell organization like NORML, etc about it so they could tell all there members! again do what the immigrants did, use myspace and the internet, tell friends and family, write the local newspapers! make flyers and pass them out. spead the word at school and work, you know. tell news stations about it so they can cover it! shit like that. wouldnt it be crazy if "we" just a bunch of people talking about weed on this site caused one of the biggest movements in world history over the legalization of CANNABIS! wow
