Get your walking shoes on, Denver. It’s time to march. Today is the 13th annual Global Marijuana March and here in the Mile High City patients and advocates will be making the 3.6 mile march across the city in support of our favorite plant for the fifth year in a row.

The Global Marijuana March is a rally held across over 250 cities worldwide since 1999 and is held every year on the first Saturday in May. And it’s not all about ending prohibition. While many march to show support for cannabis legalization, the event largely serves as a celebration of our culture in general. It’s like 4/20 all over again.

Still, expect to see protest banners flying high downtown today. Marchers will assemble at 10 am in Lincoln Park–across Broadway from the Capitol–and will begin marching at noon. Crowds will make their way to Columbus Park at 38th and Navajo, where there will be music and speakers until 6 pm.

Support a great cause by sponsoring a marcher for $4.20 per mile–just $15 for the whole march. All proceeds will be donated to the Legalize 2012 initiative, the 4th of July White House Smoke-In, and the Denver 420 Rally Coalition.

Even if you can’t donate some spare change, stop by Columbus Park for the festivities or join the march yourself. The route begins at Lincoln Park and goes down Sherman Street to 20th Street, over the 20th Street Bridge, and north on Osage Street to Columbus Park.
