It's on the outside.

I didn't open the electrical panel.

What do you mean there's nothing attached to it? Inside most panels there are 
two "bars"; one for ground and one for neutral, plus an inter-tie at the main 
panel. There are different rules, depending on whether it's a main panel or a 
sub-panel.

Did you measure the potential at the bar, and whether there is potential 
between neutral and ground?

I have a house POP where the electrical service had a grounding bar

Is it possible that the grounding bar is grounded internally somehow?
Or maybe the whole electrical box is grounded already and therefor that bar is 
also properly grounded?

Just never seen that, and am thinking it's more likely that they disconnected 
the grounding wire to a grounding rod during landscaping.
I haven't had a chance to really dig around their service conduit to look for a 
grounding rod, but none was immediately visible.

I went ahead and tied in my box grounding bar to that grounding bar anyways.
