It's time to bring out those camoflauge fatigues and combat boots - or maybe just a tie dye shirt and some sandals.

About 250 people plan to attend a marijuana boot camp Saturday at Regis University in Denver. The daylong event is designed to train people in the tactics of activism when it comes to reforming laws regarding marijuana.

Hosted by Denver groups Safer Alternative For Enjoyable Recreation and Sensible Colorado, the 2008 Colorado Marijuana Reform Seminar and Activist Boot Camp will focus on "strategy, communications, citizen lobbying, grassroots outreach, the media, and the nature of state and local marijuana laws."
