Boston, let's talk space savers because snow doesn't mean parking chaos. Whatever you can use to block the spots, the more the merrier. #boston #snow #spaces #shorts I left this morning, I put this chair in my spot, hoping it'd still be here when I got back and it was. Here's the rule, you can only use space savers during an official snow emergency. No emergency, no cones, no chairs, no trash cans, no vacuums. Once the the city ends the snow emergency, the clock starts. You've got 48 hours to keep that space saver in place.
