So now that I've had grounding installed in my house, I'm looking at my
electrical box and I don't see where the ground wire would go.

I won't be doing my own work of course, I'm not knowledgeable enough, but
before I start asking electricians to install new romex and grounded outlets
I would like to know if its even possible with my current breaker box.

That's my box, a GE panel, room for 2 more circuits, given this arrangement,
how would a grounded circuit be run? Would I have to replace the breaker in
order to accomplish this or is it a matter of connecting the ground to the
bus where the neutrals run?
