I bought the "Hold the Line" strap for my brother as a Christmas gift, the next day he asks me what the number was on the card it came with. I told him it was a serial number that goes with his strap. He then told me it was the exact number as his badge number and was trying to figure out how I knew his badge number. I couldn't believe it! It was fate! I was stuck between two different straps but loved the Hold the Line one and knew it would be perfect for him, little did we know HOW perfect it really was!
