Proponents of a Colorado ballot initiative to legalize marijuana took a long-overdue step toward being taken seriously with a straight-laced billboard supporting their position. Their tone is moral rather than libertarian ("For many reasons," states the headline, "I prefer marijuana over alcohol. Does that make me a bad person?") and lacking in the usual High Times imagery one associates with pro-pot activism. It's clear they're trying to put a normal face on their cause, and while some may see it as selling out to reach a demo that doesn't always look like it sleeps outdoors, this is a more honest and accurate representation of most pot users than many others I've seen over the years. Also, given the billboard's phrasing, it took some balls to place it above a liquor store.
