After applying to about 40 firms and being repeatedly told "the summer class is full" I gave up and decided to study and work abroad in London through a program at my law school. I hadn't tried judges yet, tho it worked for other people, as I figured studying and working in London would be a great opportunity for my sanity as well as resume.
From what I've gathered from friends and others I've talked to most 1Ls work somewhere for free, usually a local judge, a friend of the family, or some not for profit agency (such as legal aid).
