Inquiring minds want to know (specifically my DH)! I reminded him that there are street sweepers. In fact, we had a super positive experience with One of the sweepers a couple of years ago. My DS dropped his caramel apple on the ground and started crying. The sweeper asked if he could grab a new apple for him and brought one back. Made my DS's day! Back to topic. My DH wants to know if they hose down the streets every morning to keep them clean or if they have some secret cleaning method. He thinks there's more to it than the street sweepers. Anyone know their cleaning methods?
