It's a holiday weekend, and alterate side of the street parking has been suspended on weekends through October, yet on this Labor Day morning, people woke up to discover that all the cars parked on the even side of the street--the north side of the long east-west streets, the east side of the north-south streets--had been studded with tickets in the night.
I recall long and tedious discussions in Common Council Police Committee meetings about on which holidays alternate side of the street parking should be suspended and on which it should be enforced. Apparently, Labor Day didn't make the cut, but the list of holidays that did and those that didn't seems never to have been made public. Since the point of alternate side of the street parking, at least when there is no snow on the ground, is to allow the street sweeper to clean the streets, and the person who drives the street sweeper presumably does not work on holidays, it would be logical to suspend alternate side of the street parking on all national holidays. It would also make it easier for people to figure out the rules and abide by them, but logic doesn't seem to have much influence on Hudson's overnight parking regulations.
