I noticed the rod I attached the ground to is rebar.
Is that normal.
It sounds like you have a "UFER" ground system. It's becoming more common to see the foundation steel used as the primary grounding electrode. Codes recognize this as an acceptable grounding electrode that is generally superior to one or more driven rods. (Often, the impedance of driven rods will be several orders of magnitude greater than that of the "UFER" system. The ideal is a very low impedance.)
