This is a quite accurate map of the repeater system. (Note that as of now, the remote receivers are not active and the 147.225 receiver is with the transmitter in Hillsborough. The voter system is being upgraded and other adjustments are being made.)
Use standard Google Maps controls to get more geographic information. For example you could center the "A" site on the map, then zoom in as far as possible (you may have to refine your centering along the way). At maximum magnifiction in the "Hybrid" mode you can make out the tower and related sheds as seen from the above.
