The 2013 GMM-420 city lists have cities for either event: Global Marijuana March or 4/20 events. Some cities do both events. Some city pages need updating. City pages can be edited by anybody without logging in. Please add links.
Click the 4/20 column header a couple times to put all the cities with 420 events at the top. Click the City column header to put the list back in alphabetical order. If you are unable to click the column headers, then click on "full site": Full site / Mobile.
May have forgotten a few cities listed on the 2013 map.
