This sign informs local residents of where and when the garbage trucks will stop and that they should bring out their trash at those times. There's only a two-minute window between 16:58 and 17:00. Apparently the city government forgot that most people have jobs and don't have time for this, but they still remind us we're not supposed to leave our trash on the ground. There's been some improvement with public trash cans, but many major avenues don't have them.
