Good Friday morning. It's 4/20, National Weed Day. (Primer for never-stoners.)
Situational awareness: It's the 19th anniversary of the Columbine High School massacre, and school walkouts are expected nationwide.
- Arizona teachers voted for a statewide walkout next Thursday to protest pay.
Chicago readers: Please join me Monday at 10:30 a.m. for a conversation with Mayor Rahm Emanuel about the future of the city and the country. RSVP here.
