I thought it was 2014, but Ron said he missed the 2014 regional so it must have been before that. But the only other regionals we hosted prior to 2014 were 09, 10, and 11. The 09 and 10 regionals were the years we went to Austin supers. I was in the Army during the 10 and 11 regionals so I wasn't able to attend. That means it would had to have been the 09 regional if I'm correct that it was 2014 or earlier, but I'm pretty sure it wasn't that far back.
@Ron Swanson, did you maybe attend Friday/Saturday games that year and leave late Saturday before the SHSU game? If not it would seem the red LaBaron was some year after 2014. Maybe 15, 16, or 17.
