Summer Jobs

Does anyone have a job that is just seasonal? I am a teacher. I have been a leave replacement for over two years and in the fall, I have a leave replacement once again. It really looked like I was going to get a permanent position, but of course, my district ended up having to cut one position in my department. I am trying to find a summer job so I can put some money aside in case I am left jobless halfway through next year. I was thinking of waitressing, summer camp, or maybe a receptionist job. I have worked as a records clerk in a hospital. I have applied a few places and I went on an interview for a summer camp yesterday. I figured I would throw this out there on this board and see if any of you have any ideas! Thanks.
