In my little bitty itty research I've found that 044 either produces a 44 double again and stops or at least 4 

04 pairs so lets see what we've had this month 

044 hit on December 3rd 

they came back with 064 on December 5th

they came back with 470 on the 12th 

Could we possibly get another two 04 pairs this month .......hmmm makes ya wonder. RESEARCH your state this is NC pick 3
