Hey Gennee, that's great!
Does your friend already know about the No on Prop 102 website, and Arizona Together?
www.aztogether.org
Also, if he's near either Phoenix or Tucson, there are 7 Straight Nights vigil events planned for both of those cities. 7 Straight Nights in Arizona is themed around saying no to divisive ballot initiatives like Prop 102 that divide our community, neighbor against neighbor. Perhaps he would like to attend one of the vigils?
