So, what a small world. The German version of TSA sent me to secondary screening.
Turns out they thought my CODA could be a weapon, or possibly a weapon magazine.
Yes, they wanted to see me play it in the airport...
I also was not handcuffed, and they asked questions because they had never seen one before. I told them what I could, and about how fun it was.
Who knows, we may get some new CODA owners from Germany in the near future.
