YES! Throughout southern Westchester, parking rules are strictly enforced because I’ve received tickets in Eastchester, Mamaroneck, Larchmont, New Rochelle and White Plains over a period of years. NEVER assume you will get away with parking illegally for “just a few minutes.” Garth Rd. is always busy and has very limited parking considering the number of shops by the train station.
As for Election Day specifically, I don’t know but I would consider Election Day as a regular day. It’s not one of the Federal designated holidays.
