The path to Palo Alto Medical Foundation is paved with cigarette butts in more ways than one! When my family decided to pick up trash on Earth Day, we headed to the bike path that runs along the train tracks between the Homer tunnel and Embarcadero. The stretch where we tidied things up was only about four blocks long, but thousands of cigarette butts awaited our gloved hands. Along the backside of PAMF the density of "ciggyboos" (as my five-year-old daughter called them) increased dramatically. The irony was not lost on us: the more you smoke, the more you need a doctor!
