I'm so into circuit courts!
Really?  Are you a lawyer of some kind or just like cases?
no, i just like to read about courts and stuff. I just learned the core concept of circuit courts requires judges to travel to different locales
Interesting!  I did not know that.  So, do they actually travel or was that just originally what they did?
they still travel to ensure wide visibility and understanding of cases in a region
What kind of cases do they usually preside over?
any type of cases! 
Is it just one judge or is it a panel of judges, like how the supreme court is set up?
it depends on a country but in the US a judge usually travels with a group of lawyers
Oh.  Are the group of lawyers a support element or do they actually litigate in the various cases?
