Where can I look for summer job opportunities?

Honestly you are better off going into places that are franchised and asking if they have applications and that will increase your chances of getting hired. Not all Mcdonald's or fast food places are company owned and the ones that are franchised typically give out paper applications to those who ask for applications. I used snagajob.com so yes it will help you to go there since they do have part-time opportunities there, but just don't get discouraged and continue to do what you have to do to get hired.
