Burning Christmas tree on my block!

A few weeks back I was sitting here at maxwell's house of caffiene.
(my local coffee shop) and noticed a burning Xmas tree across the
street. There were a bunch of discarded trees out in the city
streets, and I'd noticed a couple on this block on my way to get
coffee. Before I knew it, everyone in the coffeehouse was staring at
the burning tree as the fire department pulled up in a big red fire
engine. The firemen jumped off and quickly doused the fire, (it was a
tiny waist-high tree) then stood there for a few minutes talking with
their hands on their hips. They probably each had a theory of how the
tree caught fire. You can see the tiny fire in the middle of this pic
