It was 24 years ago, but Michael Aguilar remembers the scene like it was yesterday — emergency vehicles with lights flashing, neighbors watching, and silence. He had just come home from a business meeting to find that a drunk driver had veered off the road into the yard where his 5-year-old son and a friend were playing. The car narrowly missed his son David, but David’s friend was seriously injured. He would make a full recovery, but not before spending a week in the hospital receiving treatment. The driver was another neighbor — an alcoholic who spent some time in jail after the incident. Right away, Michael put a sign in his yard aimed at the neighbor: “If you drink, don’t drive. Get help instead.”
