Driving down to work from the foothills, saw a sign
that there's going to be a controlled burn not
far from my house... while approaching a hill,
saw a puff of smoke at the top. I assumed it was
the exhaust from a car ahead of me and I slowed
slightly, but when I hit the crest of the hill
saw that there was no one ahead for miles;
the smoke was coming from the underbrush at
the side of the road. I did not stop to investigate.
