Jimmy I know for a fact that any homes in 92126 are served by the SD unified. Thus if you are off of calle cristobal in 92126 then your kids are going to mira mesa high school and associated schools in mira mesa.
Now if you are in 92121 down at the far west end of calle cristobal I am not positive which school the kids would be going to. You can check with sdusd to find out. It is a pretty easy process. I have a sinking feeling your kids still end up going to sdusd but I could VERY WELL be wrong.
