Ever wondered what it takes to pull the Glads annual Sing for Santa concert off?! For starters - it takes this map! This #BTS photo captures just a part of the giant arena map used for seating all of the 32 elementary school choirs participating in the concert during the games. Don't miss out on this year's festivities - the Glads are at home both Saturday and Sunday! 🎅🎄 #GoGlads #S4S2014 #GWTvsCIN #GWTvsSC
