I am currently employed at the Dunkin Donuts in my town.  Prior to that I worked at a local Burger King.  Although these are rather low-entry jobs, the learning experience is valuable. 

Over the summer I worked doing archiving: organizing and handling historic material.  I sorted through pictures and artifacts to piece together an entire family history. 

I have also worked at the "Kerriville Music Camp for Teens" as the camp videographer for the past two summers in Texas. Basically I spent a week or so in the camp documenting the workshops, the social environment, and the open mics. The first summer they loved my work so much they asked me to come do it again and this time paid me double.  It was an excellent opportunity that I not only learned a lot from, but had a lot of fun doing.
