Carmel-by-the-Sea, a small city in Monterey, requires visitors to obtain a permit to wear heels higher than two inches in public. The law, passed in 1963, aims to prevent accidents caused by uneven sidewalks due to tree roots. While the police do not enforce the law, the permit is issued free of charge and serves as a quirky souvenir for many visitors. The city has a history of unusual laws, including a previous ban on consuming ice cream in the downtown area to prevent sticky sidewalks.
