[OC] I’ve been recording what time the garbage truck picks up my trash using my doorbell camera for the last year and a half. It seems roughly every 8 weeks, they have a “training truck” that comes by much later in the day.

[OC]在过去的一年半里，我一直在用我的门铃摄像头记录垃圾车取走垃圾的时间。似乎大约每隔8周，他们就会有一辆 "训练车"，在一天中的很晚的时候才过来。
