I have 2 DC's one for each subnet.  DC belongs to 60.x and DC2 belongs to 62.x.  Each DC dns server should be pointing at the other?  Keep in mind they are in the same domain, however, they are in two geographic locations.  I need to know if I have them set correctly.  I have DC and DC2 on the name servers tab.  I also have them listed on interfaces to listen on.  Is this correct?

Each DC should have itself listed as the primary DNS entry in the TCP/IP settings for their NIC.  They should list the other DC as the secondary DNS entry.  If Internet access is also used, you would list your ISP DNS server as a forwarder address.

You can have them looking at themsleves only for primary dns, and as above configure forwarders to the outside world if required. Cleints can be configured to use their local dns as primary and the other sites as a secondary.
