You can be in the border zones for 36 hours without a tourist card, and you don't need a TVIP either. I assume that these border folks were the Mexican authorities because usually the US authorities are clueless about Mexican procedures.
Glad to see some folks riding over there. Exploring that area is on my bucket list.
