I was unable to fit my stand in my suitcase or carry-on and my System 4 table clamp did not arrived so I had to resort to a rock in a sock for my frame weight, which I put in my carry-on. Going through security they flagged my bag and asked if I had glass. I said “no glass, just a rock in a sock”. Well, it had to be tested for me to proceed to the gate. The TSA woman was very kind when she let me go, but asked “is there a story?” How do you explain ANG seminar and frame weights?
