Sea Isle City - Uninformed? The Plunge and the Run/Walk for Autism are two events. Funds from the Plunge go to the town's Chamber of Commerce, not LaCosta, therefore it's the town's event. Being involved this year, I know that Bennett of LaCosta donated thousands of dollars in time, cash, goods, and security services towards its success. He also worked very closely with Mike Monichetti of Mike's Seafood for benefit of the city and autism. For our money (an owner and taxpayer), and the city's benefit, these are two great guys!
