There are still many opportunities for summer employment, to provide you with a full time job now and the potential of part time work later on.
Camps
While most of the recruiting happens in the early winter months, many camps, both day and overnight, still need to fill certain jobs such as cooks, wait-staff, cleaners. It may not be as glamorous as being on the water staff or being a camp counsellor, but you are still out in the fresh air, and you do not have the responsibility of taking care of the campers. Check with your local day camps in your area, as well as any overnight camps you would be willing to live at while working.
