A school located in Rancho Penasquitos in San Diego that is upper middle to upper class Asians, whites, and a mix of many races, but mostly asians and whites. They go to the school with the a vice principle that i believe broke the record for having the fattest ass ever (Mr. Currigan). Newly Remodeled and more gay than ever. Took away the little field, became more strict and have fucking ugly teachers. But most of the kids who go there are gonna grow up to be successful because all the awards theyve won, unless you are one of the many who do drugs, then you will just grow up to be fuckin awesome, Especially the pot-smokers.
