Grounding (can you believe it :-))


This weekend I pounded an 8' piece of 1" copper pipe into the ground by 
our house.  Then I was thinking,  should I put in more than one pipe?  If
so, where?  This pipe is about 10' away from the house power ground, and 
therefore I probably shouldn't put my grounds too much closer.  So, the
question I am asking is how far should T.C. grounds be from the house ground,
and how far should each ground rod be from the next?  Also, how many pipes
are necessary?
