Each state has a number of clubs that have teams that play in a league where once the state champion is crowned are eligible to play in the regional cup and national cup.
In SC only the Challenge league champion can play in the subsequent tourneys. No long ago a league was created for the number 1s and 2s of each state to create a highly competitive environment. this is caleed the R3PL which is divided geographically into east, south, north, west.
This the clif notes version, there are other national and regional series for classic cup winners, etc.. but the bottom line is the highest level are the ones you have been reading in these forums
I might be wrong but examples
SC it is the Challenge league
Ga is Classic 1
NC it is the premier league (no relation to R3PL)
