As expected by me (and NC Pat), Grace did fly to the North Carolina Agriculture Research Station and private Catfish farm east of Plymouth, NC (DARK BLUE pointer Jan 18 1pm). However, she did not stay there. After just one day she flew east to the Alligator River National Wildlife Refuge in Dare County, NC.
What is incredible is that Grace flew into North Carolina on Jan 13, 2015 and did the same thing on Jan 13, 2016. Even more remarkable is that Grace has returned to the same exact place in the middle of Alligator River NWR. The GREEN lines are in 2015 and the ORANGE lines are 2016. The WHITE arrow is the location of Grace as of this satellite map on Jan 22, 2016 at 8:00pm. Click on maps to enlarge.
