Mill Avenue and the bars and clubs of downtown Tempe were packed with tens of thousands of partiers, costumed revelers, and others in the mood to celebrate Halloween on both Friday, October 30, and Saturday, October 31. There were big parties and events happening, throughout downtown — like the Monster's Block Party at El Hefe and the Monsters Masquerade at Fat Tuesday — while Mill Avenue itself was shut down on Halloween night and became an informal street party with countless people sporting getups.
