I will find the hospital he went to in 7th grade

AC/DC on The Black Ice Tour went to MO three times. St. Louis, MO once on Jan. 13th 2009 and went to Kansas City twice. Once on Jan. 21st 2009 and again on April 11th 2010. Meaning he was in 7th grade in either 2008-2009 school year of 2009-2010 school year. Now unless the concert tickets he got were for a show out of state this narrows things. I’m assuming based on context clues with the farmhouse around the time he was probably in the KCKPS - USD500 system. Meaning the hospital would have to be in this region as well. Anyone want to help on this journey I’ve created?
