As a general rule, the longer you've been out of school, the less your UGPA matters in the admissions process. They will look more closely at your LSAT score and work experience since your undergraduate years. I think that if you include an attachment explaining your poor undergraduate performance (many schools ask for this on the application anyway if applicable), it well help them to put your GPA into perspective. Time is definitely on your side as far as minimizing the impact of a very low GPA. It will also be very helpful if you have some significant career accomplishments since graduating college. I definitely think you should apply to some better schools. Good luck to you.
