There could be another explanation. John Kerry is so well liked in his Louisburg Square neighborhood that his neighbors probably donated their snow to him to show just how much they care for somebody who moves a fire hydrant to ensure he has a parking space in front of his home. If I lived there, snow would be the least of the stuff that I would dump on his doorstep.
LOL!
Perhaps his neighbors could move it back while he’s away, encase it in a solid block of ice, and when it melts, and when he notices, they could tell him to blame it on “global warming” freeing a rogue glacier that just happened to move the hydrant back to its original spot.
As for donating snow, there’s a youtube video a guy made a season or five ago. Some obnoxious woman did something while shoveling her car out, or took his hard earned cleared space, or maybe stole the shovel off his porch.
He managed to borrow a snow blower, and did a pretty good job of encasing her car the following night.
