After Collier County was named, Collier was quoted as saying: "When I first came here on holiday with Juliet, I never expected that I would buy a whole region of it, nor did I expect to pay for the new Tamiami Trail, or half the things I've done. But I really didn't expect to have a whole county named after me."[6]
