New Year's Day 👥

On New Years Day the weather is warm, so you can pack a lunch and picnic on Mission Beach, take a cruise on one of the excursion boats, or sit back and relax and watch the Rose Parade, as do many Americans on New Year's Day. It is also a tradition for many Americans to eat black eyed peas and some pork on New Year's for good luck, so these types of dishes will be offered on many of the local restaurant menus around town.
