I grabbed this TB from a Hotel today in Dothan, Alabama because I checked out the mission and wanted to help. I see that the TB has been floating around since 2011 and is still about 13 states short of its U.S. mission (not counting territories). I can feasibly check off 4-9 of the 13 between now and December so if the owner is ok with me holding on to it for a couple of months I will catalog my visits in each of the states I visit. Thanks for sharing!
