Law School Discussion

I attend school the University of Texas at Tyler.  Without exception all of the people I have met on campus that want to practice law, want to attend law school in Texas (approximately 10 students).  I personally did not consider attending law school outside of Texas until the pre law advisor encouraged me to look at colleges outside of Texas.  I was wondering if it is normal for most students to generally only consider law schools in their state, is it a phenomenon unique only to Texas, or is it just coincidental that I know 10 other people that only want to go to law school in Texas?
