I got one when I moved this year. Put the signs up (I printed them myself with a hard copy of the permit)... it rained and some fell off. Went to the police station to get more. Highly recommend just getting the card stock/poster type they have at the stations. But it didn't matter much in the end. Because by the time the moving truck arrived, someone took down every sign, and we had to unload from the middle of the street anyway. The movers stuck the permit in their window and were fast. Still waiting for the permit bill to come in the mail.

Still, I would do it again. It beats getting fined if some busybody Karen type calls the city on you. At least you will have done your part, and Karen will have to just stay mad.
