GREENFIELD, Wis. - A massive garage fire in Greenfield Wednesday morning, April 14 led a nearby tree trimmer to drop his saw and start knocking on doors. His actions may have saved more than one life. Just before noon Wednesday, the garage was engulfed in flames near 49th and Morgan in Greenfield. "So we were taking down a couple trees for the neighbor and we were working and we smelled it -- didn’t think much of it. Thought it was a bonfire," said Samuel Villafuentes.
